v5926 is very unstable

[qdii]

Hey,
I have taken the source code from trunk this evening and codelite keeps crashing:

codelite: xcb_io.c:178: dequeue_pending_request: Assertion `!xcb_xlib_unknown_req_in_deq' failed.
[xcb] Unknown request in queue while dequeuing
[xcb] Most likely this is a multi-threaded client and XInitThreads has not been called
[xcb] Aborting, sorry about that.

Sometimes it crashes just after codelite has finished initializing. I will compile a debug version and try to provide a callstack.

I recompiled with --enable-debug and --enable-asserts and everything works perfectly. I then recompiled without those flags, and crash every time I launch it. Some more information here:

[xcb] Unknown request in queue while dequeuing
[xcb] Most likely this is a multi-threaded client and XInitThreads has not been called
[xcb] Aborting, sorry about that.
codelite: /tmp/portage/x11-libs/libX11-1.5.0/work/libX11-1.5.0/src/xcb_io.c:178: dequeue_pending_request: Assertion `!xcb_xlib_unknown_req_in_deq' failed.

Compiled with GCC 4.7.1 on a Gentoo, 64 -bit architecture. libxcb is version 1.8.1-r1. I can provide more information if needed

Hi,

I dont see any crashes on this kind here (ubuntu 12.04, 64)
In addition, codelite does not make any use of 'xcb_xlib_unknown_req_in_deq'

Are you using GTK 3?
Which version of wxWidgets are you using?

My guess is that it is a wxWidgets bug - as I dont see any crashes here (GTK2) both in debug and release mode

Hi,

I've tested a release build of r5926 here (debian wheezy: gcc version 4.7.1 (Debian 4.7.1-7), libxcb 1.8.1-1) and can't make it crash, so I doubt that it's an intrinsic CodeLite issue.

A few random suggestions:
Which wxGTK are you using?( I just tested against both 2.9.4 and a recent svn trunk.)
Try temporarily renaming your ~/.codelite, in case it's caused by some particular setting or corrupt configuration.
Try building with -g -O3 (or whatever your optimisation setting normally is). That might get it to crash, but still produce a useful backtrace.
Have earlier CodeLite versions not crashed? If so, it would be great if you could bisect (try building/testing the version mid way between r5926 and the last known good one; then repeat with the new middle version; then repeat... until you find the earliest version that fails).

I hope some of the above helps.

Regards,

David

Hey guys,
I have been unable to reproduce the crash with "-O0 -g", but I crash a lot in O1, O2 and O3.
For the last crash I observed, gdb signals a buffer overflow with this callstack in thread 21

I understand that this is not helping a lot, as the buffer in question could have been allocated in so many different locations.
The good news is that, running codelite in valgrind shows a lot of errors that are related to wxGTK, so I will investigate on that side for the moment.

(errors given by valgrind: http://bpaste.net/show/54671/ )
