A recent change to arbprogparse.c on Apr 28 is causing references to vertex
attrib zero to crash. I'm not entirely sure on how it is supposed to be
handled now, but my guess from trial and error is found below. Someone please
take a look.
Changes:
Be more strict on the vertex attrib array bounds and use an absolute zero for
vertex attrib zero.
