[wxPython] 2.1.16 core dump problem on Irix

Hi,
I compiled wxGTK 2.1.16 on my O2 and it works fine. Then I compiled wxPython
2.1.16 but when I run the python demo I only get:

     Bus error (core dumped)

For my other wxPy programs I always get a "Segmentation fault" message.

My configuration is:

Sgi O2, IRIX 6.5

I compiled wxGTK with native CC, n32 libs, with:
./configure --with-gtk --with-opengl --disable-dialupman

I built wxPython with:
build.py - b CCC=CC CC=cc OTHERCFLAGS="-DNULL=0"

The last working version of wxPython was 2.1.13. After that, I was not able to
run wxPython on my O2 anymore. I have to add any flags instead? Should I try to
recompile it with gcc? (I used it for the 2.1.13, if I remeber well) If yes,
it's better to recompile with gcc wxGTK also?

Thanks,
M.T.
