Tim,

Thanks, this is the kind of thing I suspected was probably hiding out there.  I assume these MachO fast unwind restrictions also would prevent doing non-leaf frame pointer elimination and redzone optimization?  Do you think these restrictions are currently captured in the tests that I modified?  Perhaps some of these tests need another non apple triple run/check so we cover both paths?
