Fix Cycles crash in certain hair configurations
The issue was caused by hair shader setup setting normal to a non
finite value, which then gets used to create a ray with non-finite
direction, making BVH traversal to run out of stack memory.
Happens with 150_0040_A.lighting.blend frame 112 of the Sprites
project.
