Ah interesting.

I figured purify would determine the UMR at the point it reads from the  
heap to push onto stack (In which
case UMR should not go away with that transformation). But it could be that  
because of UMC class that is not
the case.

Re-assigning to me to dig some more.
I will pretend like the UMR was for "2 bytes" and re-investigate.
