crash: codeblocks wx2.6.1 unicode

rickg22:
Well I see some issue here...

Apparently the saving of the sash position is an awful hack. I just fixed it, and made sure it wouldn't crash (null checks nearly everywhere :-P ).

Also, I made sure that the config reading is only done ONCE, so that'd save us a few clock cycles. I'm committing into CVS right now.

zieQ:
Hum, another crash on exit in HEAD and V1 with wx2.6.1 (no unicode), same bug here again about sash position :(

Anyway, I do not understand why event queues are not emptied when closing the application. May the problem be caused by the use of threads or processes? Seems to me that many bug fixes are just ugly hacks, IMHO there's a subtle problem that need to be fixed in C::B core! Any ideas?

I can't wait for the thread pool :wink:

rickg22:
Bug fixes aren't ugly hacks - some new features are (like the auto-hide message pane). Bug fixes are well... patches for the ugly hacks :-P Of course, good fixes involve a complete refactoring of certain modules.

Anyway, It's not that the event queues are not emptied on exit - it's that some event loops become recursive due to the use of wxYield, unless you enable the "crash protection" tweak. But then again, I'm not sure if you have it enabled.

Also, i think some gtk operations trigger a main event loop (not wxwidgets, but gtk's native), and this might mess up event handling (yes, gtk is ugly). Mind posting the backtrace, please?

zieQ:
Oh sorry, I was talking about windows version. Anyway, I expect no crash when I use a program, so I have not set crash protection "feature" which resemble to a ugly hack for me :lol: Can you explain the wxYield problem and its solution or point me to the thread which explain it?

Sorry but I just get bored with the crash on exit, I have seen many of them while bug fixing the wrong imports for quake3 project.

Agree that gtk is ugly but I was thinking: wxWidgets is supposed to handle all the ugly stuff, isn't it?

grv575:
Same results. wx2.61, windows, nonunicode, latest cvs. Two crashes

1. xtra_classes.cpp:94
-- if(w1 && w2 && w1->IsShown() && w2->IsShown())
IsShown() crashes things???

hard to debug as the OnUpdateUI() event fires every time the window is switched to.

2. compileroptionsdlg.cpp:1024
-- void CompilerOptionsDlg::OnAddVarClick(wxCommandEvent& event)
{
--

makes no sense :)
