Sometimes when using gdb with my program I see error:
Program received signal SIGFPE, Arithmetic exception.
[Switching to Thread 1024 (LWP 2340)]
0x405cdcfb in _mesa_test_os_sse_exception_support () from
/usr/X11R6/lib/modules/dri/tdfx_dri.so
This is not my program fault, because there is same message with glxgears and
other OpenGL applications. However I remember - sometimes I could debug OpenGL
program without problems!
