Issue here is the mesh contains nan vertices cause mikktspace's MergeVertsFast to go into an infinite recursion, it shouldn't crash, but these are likely to cause trouble.

The mesh is corrupted. You can see this if you run C.object.data.vlaidate(True) in the py console. So the actual bug happened at the time mesh was corrupted and that's what is to be fixed. But for this we need to know exact steps reproducing such a corrupted mesh.
