Thanks for the pointer.  I had this bug marked as one I wanted to look
at, but it was buried under a lot of other bug reports.

The reason why this problem occurs on IA-64 seems to be tied to the fact
that we don't have reg+offset addressing modes.  We thus get different
RTL generation and different RTL optimizations, and this happens to
trigger the longjmp clobber warning code because it is over simplistic
(i.e. stupid).
