Sorry, I should have debugged a bit more before writing:
Following up to my last message, using "fpsetmask" to ignore all exceptions
except division-by-zero, the program works.
Program received signal SIGFPE, Arithmetic exception.
0x281824d8 in gl_x86_transform_points3_3d_no_rot_raw ()

I've got a small program that will cause a segfault:
Program received signal SIGFPE, Arithmetic exception.
0x281824d8 in gl_x86_transform_points3_3d_no_rot_raw ()
from /t/video/libGL.so.3
(gdb) bt
#0 0x281824d8 in gl_x86_transform_points3_3d_no_rot_raw ()
from /t/video/libGL.so.3
#1 0x80

the rules are for using bzero, something may probably have
to be added to configure to support/not support this. (bzero is much faster
than memset on freebsd)
Please let me know if you have any comments or suggestions.
