If you use GNU/GCC compiler, you must pass "-g" to g++ to get a debug-version of your app.
It's also useful to compile wxWidgets for debug. Use "--enable-debug" or wxconfig to achieve it.

Once you have a debugging version:
gdb myapp
...crash
bt

Hi there,

3 years later the problem still persists.

Presumably it is not wxWidgets - it is a system issue with XOrg MESA with Intel Chipsets:

See Comment 8

Hope this helps someone
