Title: Bug in svn8974 with wxMSW-2.9.4
Post by: stefanos_ on April 09, 2013, 09:24:52 am

I have successfully compiled both CodeBlocks.workspace and CodeBlocks_wx29.workspace, but the latter build crashes upon startup; the way I have built wxWidgets is with custom version of wxBuild batch script from wxPack, according to my needs.

I have used gdb with backtrace to find the error message:

Code

Looking at the backtrace, I don't see much useful information, because it only have one call-stack shown.

@ollydbg: I wish I knew more about debugging executables.

@xunxun: Nothing changed at all;
