I am not sure of anything at the moment, although I have found one
instance of a crash with none of the XenServer patch queue whatsoever.

At the moment, I have narrowed the problem down to a handful of
instructions writing 0s into a well-formed region of the stack. 
Clearly, this is not correct, and every tweak of the debugging causes
the problem to jump around.
