Debug Statements
« Reply #15 on: December 31, 2010, 03:59:43 pm »
Okay, I added a bunch of debug statements around the "File-Open" dialog box, and it is crashing at "if (dlg.ShowModal() == wxID_OK)".

Here is the generated output from my debug statements.

/file_dialogs/file_new_open/filter    -->   
Filters    -->   Ada files|*.ads;*.adb|AngelScript files|*.as|<A very long list of file types and associated extensions>|All files (*)|*
GetFilterIndexFromName
Prior to wxFileDiaglog dlg(...)
Path --> 
After wxFileDiaglog dlg(...)
Prior to dlg.SetFilterIndex(StoredIndex)
After dlg.SetFilterIndex(StoredIndex)
Prior to PlaceWindow(&dlg)
After PlaceWindow(&dlg)
Prior to dlg.ShowModal() ==wxID_OK
Segmentation fault

Any ideas on what would cause this to crash?  I tried removing the "compatibility::wxHideReadonly" from the style parameter, but that did not help.

Have you tried to run C::B with valgrind, it could be, because of some writing of uninitialized memory?
If valgrind doesn't help, build wxGTK in debug mode and use gdb to trace the crash...

Okay, I'll try that, but it does not make sense that many other programs including wxWidgets sample code work okay.  One of those had open & save capabilities.

I'm getting close to going back to Fedora x64.

I recompiled wxGTK and CodeBlocks with debug enabled.  Using valgrind, here is the output generated when I click "File - Open".  I enabled the option "track-origins" for valgrind.

After "File - Open", the start of the error dump is with "Invalid read of size 1".

I found two tickets on the bug tracker for wxWidgets.  The first shows that the bug occured in 2.6.  The other shows that the problem still occurs in 2.8 and mentions CodeBlocks.

The second bug is for windows, so it is not related...

What is your gtk+ version?

So, has anyone researched this or should I just forget RHEL 5.5. and go back to Fedora?
