Why does GPU skinning cause mesh spikes?

I’m getting some severe mesh spikes that go away when I check the CPU skinning box in the Character->Advanced tab. That is the only difference between the two attached images.

What is happening? I checked the weight painting and it looks ok to me. I tried moving the mesh via the root bone in blender to check for unweighted vertices, but I didn’t see any tearing occur.
