Hi!
The following patch fixes a bug in SEH exception handling that made it
crash with ObjC (and most likely other languages as well). The problem
is that the SEH exception handler always passes the unwind exception as
4th parameter to RtlUnwindEx, which RtlUnwindEx then later passes to
the landing

Maybe:
A replicated vector constant in which the replicated value has a single
