I was looking at xmmstack - it's a neat hack!  However, as near as I
can tell, it only fixes up %esp references.  If gcc were to copy %esp
to %ecx and then issue a memory access to %ecx then xmmstack isn't
going to fixup that memory access.  So, unless I missed something, the
leal change is likely to just mask the problem.
