crash while parsing source files
« on: March 25, 2009, 03:06:09 pm »
When I save some files codeblocks crashes.
The output is:

Reparsing saved files...
Segmentation fault (core dumped)

The backtrace is:

This continues to about 58000 deep and the gdb crashes so I can't get a full backtrace.
It doesn't seem to do it on all files either, I can send all my source if you would like too.

I'm not an expert on the C::B parser, but this looks to me like it's trying to parse a library.  This IS a source-code file you are trying to save, right?  Language C++?  Does it compile?

yes it's my own source, it's c++, it compiles fine.

also it's in revision 5486, it also happened on 5482.

I stumbled over a similar crash just some days before, that occurs only on my 64-bit linux and only with some sources.
You use a 64-bit unix, too, if I read your backtrace correctly.

Today I found the time to track down a possible problem.

I guess you use a self-compiled C::B, so it would be nice if you can test the following patch:

Code

+                break;
             }
             else
             {

EDIT:
modified the patch, a simple break to leave the while-loop is enough and decreases unneeded overhead.

first time it failed before it even started, second time it crashed after saving. It also happens on my 32 bit computer, and on the 32 bit uni computers. The bug buddy crash log is pasted after this.

No idea at the moment.

At build time, did you use a clean source-tree ?

one of the computers did, I'll redo the others and see what happens.
I'll try breaking at that function that gets called lots so that you can get a backtrace of what it was doing before it died.

Are you able to create a demo-project (as small as possible), that leads to the crash ?

I see why it crashs (most likely):
Code
parentToken = (Token *) 0x1
in RemoveToken will reliable lead to a crash, because it should either be a vaild pointer or 0.

changing the file parser.hpp and saving it causes the crash.
It also needs boost 1.38, and I couldn't get it to crash without having that in my search path, so when it asks for the boost global variable you'll have to give it the path to 1.38.

Thanks I will install boost later the day.
I hope it crashes also with 1.37 (that's the newest version in debian), but I will also download more actual sources to compile it myself.

Works just fine here (on Windows, Boost 1.38).

But: I have a modified version of CC... so probably this crash has been fixed meanwhile. Can you try another nighly?

I was able to make it crash with an unmodified C::B from trunk (r 5486) on my debian laptop 64-bit and boost 1.38.
1.37 does not crash !

So I see the possibility to find the issue this weekend.
Might be fixed with the cc-changes, because a modified version (trunk with new/changed cc seems not to crash).
But the other issue I found (see patch some posts before) does also only occur more or less randomly, depending on what the OS does with the unused memory, if we accidently reuse it.

I just tried it with no source code, just the includes, and it still crashed. So I guess it's something in boost. I also got a different crash which hadn't happened before, but I didn't save the backtrace. It may have been the one you said you fixed so I'll post if it happens again.

The only difference in token.cpp (where the crash appears is in TokenExists(...).

With the following patch, the crash should not appear:

Code
Index: src/plugins/codecompletion/parser/token.cpp
===================================================================
--- src/plugins/codecompletion/parser/token.cpp	(Revision 5486)
+++ src/plugins/codecompletion/parser/token.cpp	(Arbeitskopie)
@@ -463,7 +463,7 @@
         Token* curtoken = m_Tokens[result];
         if(!curtoken)
             continue;
-        if((parent<0 || curtoken->m_ParentIndex == parent) && curtoken->m_TokenKind & kindMask)
+        if((curtoken->m_ParentIndex == parent) && curtoken->m_TokenKind & kindMask)
             return result;
     }
     return -1;

The problem is, that I still do not know what causes the crash in
Code
RemoveToken(...)
.
I don't like a crash go away without really knowing the cause for it, so I will try to investigate further.

That seems to have fixed it, thanks.
I'm curious to know if you know which part of boost was causing the crash.
The complications of boost strike again, it finds all sorts of problems in gcc, but now it's crashing IDEs too.

I added my first patch to trunk.
Not the one that works for you, because it is part of a codecompletion update, that is in testing phase.

I've actually started getting another crash. Unfortunately the backtrace is a little useless.

Code
Thread 1 (Thread 0xb639f8e0 (LWP 22973)):
#0  0xb66520bc in ?? () from /lib/libc.so.6
Cannot access memory at address 0xbf242fe8

have you seen anything like this with your tests?

How's the progress on getting the other fix into trunk?

No, did this also happen with boost-library ?
Can you reproduce it ?

If yes,  do you have a simple test-case ?

on 64 bit it seems to be crashing in RemoveToken, my 32 bit computer doesn't say anything useful in the backtrace.
change include/tl/types.hpp and save it and it should crash.

You will probably need boost 1.38 as from last time.

Try the following patch and remove the comments around parent < 0 in TokenExists(...), that means revert the patch posted before:

Code

+++ src/plugins/codecompletion/parser/token.cpp	(Arbeitskopie)

     // m_Descendants SHOULD be empty by now - but clear anyway.
     oldToken->m_Descendants.clear();
 

We seem to run in an endless recursive call of RemoveToken as you can see on the call-stack if it crashes.
It tries to remove the same Token over and over (same idx).
And so most likely corrupting our memory.
Why this only happens on 64-bit, I don't know.

Try the following patch
I got another example that (Jens: as discussed) probably has the same root. Luckily it's way simpler and smaller that boost. ;-)

Attached is a project that consists just of header files. For me (on Windows) if I do:
- open any of these files
- change something (I do space + delete all the time - so I *don't* change content)
- save
- change again something like above
- save again
--> C::B crashes.

It seems probably be to be related to:
- the folder structure and the class "C" appearing in different namespaces
- the live parser...?!

Strangely it happens only at the second save to me.

The funny thing is, that if I also log the Tokens name
Code
Manager::Get()->GetLogManager()->DebugLog(F(_T("oldToken->m_Name = %s"), oldToken->m_Name.c_str()));
I see that not always the same recursion happens.

Another thing:

how does CC decide which class is the parent-class, if no header files are explicitly included.
For example the parent class "C" that is used by CC in "M_C.h" is in the same namespace, but there are no includes, so it is not in the scope and should lead to an error when compiling.
I think that CC should only use tokens (as base class in this case) that are visible for "M_C" (in this case).
Everything else is a guess and therefore error-prone.

I'm still getting crashes, the stack trace looks like this:

#14 0x00007f1e07a648f9 in TokensTree::RemoveToken (this=0x1307c50, oldToken=0x7f1e024715a0) at parser/token.cpp:607

#16 0x00007f1e07a648f9 in TokensTree::RemoveToken (this=0x1307c50, oldToken=0x7f1e024715a0) at parser/token.cpp:607
#17 0x00007f1e07a648f9 in TokensTree::RemoveToken (this=0x1307c50, oldToken=0x7f1e0279e650) at parser/token.cpp:607
#18 0x00007f1e07a648f9 in TokensTree::RemoveToken (this=0x1307c50, oldToken=0x7f1e024715a0) at parser/token.cpp:607

Unfortunately the crash only seems to happen in my code which is now even bigger and makes it hard to track down. But notice that the values of oldToken seem to be alternating if that helps.

The same to me, CB crashed after first save.

By the way, I'm not sure how to see the stack track.（windows XP)

Thank for the hint :D
I'm not sure that when Code:blocks crashes(not running in gdb), will it create a dump file in the installed directory?

Is there any progress on this. It's getting so bad that it's unusable. I'm getting crashes quite frequently, and I'm also getting freezes with 100% cpu usage while it's trying to code complete sometimes.
I can post my project if you want, but it's >4000 lines now so I don't know how useful that's going to be.
