Yes, because you built python with -O0; you should add at least -g to
the cflags, because here, you don't have debugging symbols, meaning the
gdb won't be of much help unfortunately.

Would it be possible for you to rebuild python and numpy with debugging
info ? I tried to look into that bug, but I can't reproduce it on
opensolaris with gcc and python 2.4
