A while back I mentioned on dri-devel that Savage cards will segfault RTCW while loading the Checkpoint demo. ( http://www.nixnuts.net/benchmarks/current/ ) The problem is in Mesa/src/mesa/tnl/t_tertex.c around lines 741 and 913.
for (j = 0; j < count; j++) { GLvector4f *vptr = VB->AttribPtr[a[j].attrib]; a[j].inputstride = vptr->stride; ... }
vptr is null in the middle of the for loop ( j=2 is null j=0, 1, and 3 is valid.) I have no idea why this is the case, but I've attached a simple fix which eliminates the problem.
Does anyone see this in other hardware? If it's only the savage driver causing this, I would say there's probably a bug in the driver somewhere.
What are the values of j, count and a[j] at the time of the crash?
