I have a problem with code that works fine in 3.1b2 and before segfaulting
on 3.1b3 and current cvs.
Unfortunately it is a fairly large app, I will try to replicate the fault
in a smaller bit of code, but some guidance as to likely causes would
be helpful.
The problem occurs in images with alpha blending only, and I get a
segfault in stages.c, line 480 :
(ctx->NormalTransform[tmp])(&ctx->ModelView,
ctx->vb_rescale_factor,
VB->NormalPtr,
(VB->NormalLengthPtr ?
VB->NormalLengthPtr + VB->Start : 0),
VB->NormCullStart,
VB->store.Normal);
Program received signal SIGSEGV, Segmentation fault.

This happens using ggimesa, voodoo or software rendering.
MMX Intel and Athlon.
