proposed patch
Yes, marking the regions of __builtin_eh_copy_values sounds reasonable
(and yes, it does fix the ICE here).
I think it would be valuable to know what's different about ubsan that
we haven't seen this same ICE with plain C++. I may spend a little bit
of time trying to reverse-engineer such a test case while this patch
goes through normal regression testing.
