I compiled 64 bit mesa now with gcc 3.4.2 from sunfreeware and it crashes, too
but with other errors.
./gears
One time I get an assertion:
146 frames in 5.007 seconds = 29.159 FPS
Assertion failed: a[j].inputstride == vptr->stride, file tnl/t_vertex.c, line
382
Abort (core dumped)

Maybe the memory has a wrong alignment and trying to read from this misaligned
memory sends
an bus error.

running the ray demo I got the same segmentation fault like mesa compiled with
gcc 4.0.2.
