Yes, this is a bug. And I've found the cause for this: setting up
synced PHI stack slots can go wrong. Alas, there's no easy fix in
sight. This will take me quite a bit of time to solve.

BTW: I've got an unresolved bug on ARM, which probably has the
same cause. Now I've got a simple test case. Thanks!
