Title: crash when use wxsmith
Post by: icequan233 on April 19, 2017, 03:16:42 pm

       Hello, On windows10, the codeblocks built against wx30 and Tdm-gcc5.1, while I use wxSmith to change a control's style, cb crashing.
       So I debug codeblocks, and I attached the picture of call stack. It seems related to wx30(I guess this is the wx's bug), the similar question http://trac.wxwidgets.org/ticket/12552 . But it should be fixed. Then I debug the
wxSmith, I can't trigger it in wxSmith, just as same as the picture.
       Therefore, I am yet not sure that it is the wx'problem or wxSmith'problem. Can Anyone helps me, Thanks very
much.

can you post the exact steps to reproduce?
Can you post the full backtrace? It would be cool if you can post it in text form. You can copy it from the debugger log tab.

You probably have to recompile codeblocks with the debugger symbols enabled so the backtrace is filled with readable function names:
In Settings->Global Variables->cb_release_type->base add a "-g"
then you have to rebuild all codeblocks:
Build->Rebuild workspace

In fact there is a simpler way: right click -> copy to clipboard or right click -> save to file.

Also it will be good if you can add symbols to wxwidgets. This will make the backtrace more meaningful.

first open a .wxs file, second, go to resource->properties,then check a style, last, save the .wxs file.
cb will crash after these steps.

I don't know about the wxSmith, so I can't set the breakpoint where the code of my steps.

Tried it, it doesn't happen on linux. Can some windows user with a wx30 build try to reproduce it?

I am building wxWidgets 3.0.2 32 bit right now; in a several hours, I plan to see if I get the problem under Windows 10 32 bit.

Edit: Note to self, need both wxSmith and wxSmith MIME plugins enabled to do testing.

Duplicated the crash on Windows 10 32 bit.
Now going to use debug wxWidgets to see if more info results during crash.

Edit:

Code

gcc version 5.1.0 (tdm-1)

Attaching crash report; it crashed twice.

Edit: Using wxWidgets 3.0.2 with patch on it to build using GCC 6.3.0.
Edit2: Now building wxWidgets WX_3_0_BRANCH to see if the problem has been fixed in that git branch.
Edit3: Problem NOT fixed in WX_3_0_BRANCH git branch; so, likely NOT wxWidgets problem.
Going to build using MinGW64 GCC 6.3.0 and see if problem goes away; I am better using GDB under MSys2.
Note: I still am very bad at using gdb, I just might be able to do a back trace under MSys2.

Can you post a backtrace/callstack from the debugger. This report is hardly readable...

You probably have to recompile codeblocks with the debugger symbols enabled so the backtrace is filled with readable function names:
In Settings->Global Variables->cb_release_type->base add a "-g"
then you have to rebuild all codeblocks:
Build->Rebuild workspace

For rebuild/recompile do you mean compile+link C::B from sources or is because  icequan says "the codeblocks built against wx30"?

Hi, guys. I found position where my steps in wxSmith, so I set breakpoints and trace it. Finally, I got the crash point,
in codeblocks SDK, the editormanager.cpp and the cbauibook.cpp, I attach the call stack. And there is some debug
information.

Debugger finished with status 0

I have some quesition. First, in editormanager.cpp:698, when running to this statement, cb was crushing.
m_pNotebook->DeletePage(index), I noticed that the m_pNotebook was initialized to nullptr and NEW in constructor, I think which is no problem. Then I step into cbauibook.cpp, just derived form wxAuiNotebook,
I also think there is no problem at this statement. I don't think it is the wx'problem, because I can delete the
page of code editor normally, and if I don't change the style, it is also deleted. So, in my opinion, the most probably reasons is m_pNotebook was released forward in constructor when called out of obeject. I means that
the NEW operation is useless, beacause the resource of constructor was released, so actually we don't allocate resource for m_pNotebook, and the adress is nullptr, so will crash here. just my guess, can anyone helps debug or
see whether it ie right.

       Sorry for the picture, the forums limits size, I crop the call stack.

This is not the crash site as far as I can tell, isn't it?
Please remove all breakpoints and let it crash.
Then go to the call stack window, right click in the window and click on the copy to clipboard menu item.
Then paste the callstack in a code or quote tags.

The crash happens because of an illegal pointer in propgrid.cpp (GetY2) in the for-loop.
getParent returns 0xfeeefee.
I can reproduce it with wx2.8 and wx3.
It either tries to access an already deleted or an incorrect initialized pointer, looking at the address, the first is more likely.
It might be an(other) optimization bug of gcc.

The true crash site is the first post, and I attached the picture. I think @jens is right, the similar question of gcc

These are not bugs, but features :)
Lets see if I can reproduce this in wx2.8 and gcc 6.x.

Sorry, but do you think you can solve the problem with the information provided in the first posts?

GCC is very solid compiler and it is very hard to find bugs in it.
Most of the times the problems are caused by bugs in the program that are manifested by an aggressive optimization.
These are still bugs in the program and not in GCC!

I am now going to apply the wxWidgets code change to IsKindOf method and verify it really fixes this problem.

Edit: It did NOT fix the problem.

Thanks you for the callstack.

I am now going to apply the wxWidgets code change to IsKindOf method and verify it really fixes this problem.

I doubt this will help.

@Jens: Are you talking about windows or linux? Have you tried with wx-master?

I tried wx3.0.2 and 2.8.12 on windows and wx3.1 (not latest) and 2.8.12 on linux.
All crash, not always, but this might depend on the value of m_parent in propgrid.cpp .

I try to dig into it deeper.

I cannot crash it, but I've seen the crash in wxsmith.
What are the steps to reproduce it?

I forget the last steps, After checking or changing the style, you need delete the page of wxs editor, It should be
crash. On my virtual machine, Ubuntu16.04, I can reproduce this crash, but not always.

I just finished building wxWidgets git master (Updated in the past 24 hours) and did NOT see the crash.
Too tired to double check my work tonight. If I confirm this; then, it is likely a wxWidgets problem that has already been fixed to git master.

Edit1: A quick search resulted in this being the change most likely to have fixed the bug.
Edit2: This is based on the guess that compiler optimization is causing the bug.

* Avoid comparing address of reference to NULL

As GCC 6 points out, the compiler is free to assume a reference is never
null, and remove such a check

This is already fixed in our version of wxpropgrid in master. This is not the cause for the bug.

Thanks Tim, many thanks. Anyway, the problem has been fixed.
Now I think that even if compiler optimization cause this problem, we also need to change
our code to slove this problem. So, it is the key that how to slove but not who's bug.

This should be fixed in latest trunk (svn r11053).
It's tested on linux with wx2.8.12, 3.022 and latest trunk and on windows with 2.8.12 and 3.0.2 .

I just tested on windows, fixed indeed. Thanks jens, this is the best method to slove it.
