I found a bad behaviour under Linux, i want to use cmake Makefile generator from Tools menu, made an entry
(Name:cmake, Executable:cmake, Parameters:${PROJECT_DIR}, Working Directory:${PROJECT_DIR}/.cmake) to configure out-of-the source build and try to run it. Result? crash. Under gdb i get onlt this as backtrace:

This is from revision 2449.
I manage to test same configuration (or similar one) on Windows machine. And what? It works... how suprising.
But i use LINUX, may someone help me to debug this problem? Maybe some instructions how this can be made. I want it fixed, i may even try to hack Code::Blocks sources.
Surprise: I mainly use linux and everything works here too (3 installations, all debian based).
Try the following please:
make clean-zipfiles
make clean-bin
make
make install
I managed to install debian unstable, get newest svn build (i use a ubuntu deb package http://forums.codeblocks.org/index.php?topic=3172.0 (http://forums.codeblocks.org/index.php?topic=3172.0)) and get crash with tools.
What i have done?
Added tool named: ln
Executable: ln
Parameters: --help
Run this and crash. Valgrind output, i have to say it is slighty different, it has slighty different trace, why? i don't have any idea, but problem is with the same element.

I contacted with one other Gentoo User but he doesn't have these strange crash problems.
One more thought, this problem is with last element of class ToolsManager, wxTimer, so maybe it could be a problem with structure alignment? But this is a blind shoot...
I can't send anything about debian configuration, nor how this binary package was created but i can give some specific informations about my system configuration, but i must say, i don't use anything weird, i never had problems with any library configuration, also i use one more wxWidgets application (aMule) and it works without problems.
Here you go:
void ToolsManager::OnToolTerminated(CodeBlocksEvent& event)
{
m_Timer.Stop(); // <-- your crash is here
m_Pid = 0;
m_pProcess = 0;
Manager::Get()->GetMessageManager()->Log(_T("Tool execution terminated with status %d"), event.GetInt());
}
It makes no sense, because m_Timer is a member object (not a pointer). The only time this could be invalid is if the ToolsManager class is not constructed yet. But this can't be the case because it's a singleton. It exists throughout the application lifetime. And, if I 'm not mistaken, you don't get the crash on startup or on shutdown, but during a normal run. Right?

This means absolutely nothing. Nil.
The fact that two apps use the same widgets lib under the hood doesn't necessarily indicate faulty usage in one of them (if one is misbehaving). Especially if that lib is wxWidgets. You can have it configured in so many ways (static/shared, monolithic/modular, unicode/ansi, etc).
I can't send anything about debian configuration, nor how this binary package was created but i can give some specific informations about my system configuration
And you really want to get help after stating this?
Well, I will ask for info and you decide if you want to give me some.
I need the output of the following commands:
wx-config --cflags
wx-config --libs
ldd codeblocks
ldd libcodeblocks.so
(I just hope you 're not using a static wxWidgets build)

I get this crash only after Tool run, on exit.
Also i examined source code of this, and know that wxTimer is member object, so i said about structure aliasing. Maybe there are some differences in compiler flags or version (this could be issue with gcc4 line), but as i said earlier, this is blind shoot.
Moloh could you try a previous revision of C::B? And also the new built I will provided today (or tomorrow morning). Thanks
No problem, if You provide build i will test it.
Here are the few configuration things:
wx-config --cflags

405: m_Timer->Stop();
Error line is with m_Timer pointer but i rather think error is about "this" pointer, not m_Timer. And additionally, why there are two errors there?
To test it i add a NULL check, and to result show it clearly, problem is with "this" pointer, so either bad object is registered somewhere as an event reciver or some other bad thing is happening. But i have no experience how exactly events in wxWidgets work. Here is output

405: if( m_Timer )
406: m_Timer->Stop();
There is also one more question, why in case of m_Timer commenting out (only in source code file, in header there was still declaration of object) things work ok.
I will still try to investigate more this problem, but hope for a help from experienced developer.
Well, time to remove some code :D
Thanks to removal of wxTimer, codeblocks no longer crash on Tools usage, but problem is still there.
I tried to analyze source code, how event is registered and added some checks. As i said there is problem with this pointer and to check this i add sth like this (all modifications in files toolsmanager.cpp and pipedprocess.cpp, all that are in the post are from toolsmanager.cpp file)
Manager::Get()->GetMessageManager()->Log(_T("This at start: %d"), this);
Manager::Get()->GetMessageManager()->Log(_T("This at end: %d"), this);
As i thought this value is different, why? Ok lets go further...
I added similar modifications to PipedProcess class (there i used m_Parent, which should be the same) and results were pretty interesting.
So it occur to me that problem was that: this pointer is okay in ToolsManger, but bad in ProcessManager...
I googled a moment... and? Here is why: http://carcino.gen.nz/tech/cpp/multiple_inheritance_this.php#downcasting (http://carcino.gen.nz/tech/cpp/multiple_inheritance_this.php#downcasting)
Read it and You would know (better whole, not only about downcasting).
Problematic line:
162: m_pProcess = new PipedProcess((void**)&m_pProcess, this, idToolProcess, pipe, dir);
// comment: i must say this is interesting hack for setting m_Process value, modify self pointer in parent from self, child instance.
I am definetly a c programmer, don't know c++ hacks and tricks, here is one pitfall, but i see someone who did that also doesn't know c++ very well. Ok i lost patience... sorry.
Prolem is still, i tried dynamic_cast and no chance, it doesn't work so probably You don't have virtual function, so either You have to modify inheritance (if there wouldn't be multiple inheritance, then there would be no problem).
Here you have a reinterpret cast with multiple inheritance:
leal -28(%ebp), %eax
movl %eax, -32(%ebp)
In words: get the address of a variable (which is a pointer) and store it in another variable (which is a pointer to pointer).
Once again: it is NOT a downcast, it IS a reinterpret cast, and, again, that's the intention.
Modifying the pointer only in ToolsManager is a choice, but really, don't get yourself confused. That would save us a double assignment to that pointer which happens to be two asm lines (because of the indirection), and just that.
movl -32(%ebp), %eax
movl $0, (%eax)
Just for fun. Here you have the code of a downcast with offset adjustment (4 bytes for this test) and which also checks for NULL (well, it really has to):
cmpl $0, -28(%ebp)
je L2
movl -28(%ebp), %eax
addl $4, %eax
movl %eax, -36(%ebp)
jmp L3
L2:
movl $0, -36(%ebp)
L3:
movl -36(%ebp), %eax
movl %eax, -32(%ebp)
Anything else to prove?
Just give me something I can test, like: Add tool with name xxx that calls yyy with parameters zzz and blah blah blah, check the value of this here and there... something like that.
Just be sure to include filename and line :)
[edit]
I just took a closer look to the line that surprised you. If you take a closer look too you'll find it's OK :)
m_pProcess =
new PipedProcess((void**)
&m_pProcess, // address of m_pProcess != m_pProcess
this, idToolProcess, pipe, dir);

Already did this here:

I all the time speak about *this* pointer in this call.
Screenshot attached. I must say i am suprised about reinterpret_cast, it works, i must eveluate why there is change there...
[edit]
After few minutes and some reading, now i am not suprised why reinterpret_cast works as in screenshot ;-)

If there was no multiple inheritance, or if at least the inheritance order was swapped, it should work, but who knows... it's the GCC 4.1 world and crazy things could happen (that just shouldn't) :)
Try this:
toolsmanager.h, line 33, from:
class DLLIMPORT ToolsManager : public Mgr<ToolsManager>, public wxEvtHandler
class DLLIMPORT ToolsManager : public wxEvtHandler, public Mgr<ToolsManager>
That should give you the same output for all casts and hopefully for the one in OnTerminate :)
I took a look at the event "construction", which is just a bunch of casts, and replaced it just as suggested in the wxWidget's manual (adding even more casts) and... voilà! The value of this is right for both calls now (good luck or fix... nobody knows).
I checked the address returned by both bunch of casts and both return the same address. It's even more confusing now because if it was the problem it should, at least, return different values.
I decided to check that 'cause I thought some evil magic there could cause it, but having the same value returned do also makes sense after all, 'cause we're playing with pointers to member functions.
At the end it could be some deep cast in wxWidget's code being generated differently by GCC 4.1, but the results of my tests just confuse me more.
For reference: sdk_events.h, line 209, from:
#define EVT_PIPEDPROCESS_TERMINATED(id, fn) DECLARE_EVENT_TABLE_ENTRY( cbEVT_PIPEDPROCESS_TERMINATED, id, wxID_ANY, (wxObjectEventFunction) (wxEventFunction) (wxCommandEventFunction) & fn, (wxObject *) NULL ),
#define EVT_PIPEDPROCESS_TERMINATED(id, fn) DECLARE_EVENT_TABLE_ENTRY( cbEVT_PIPEDPROCESS_TERMINATED, id, wxID_ANY, (wxObjectEventFunction) (wxEventFunction) (wxCommandEventFunction) (wxNotifyEventFunction) (CodeBlocksEventFunction)&fn, (wxObject *) NULL ),
Right now, the most confusing part is why that change makes it work if it seems to change absolutely nothing at all :(
