gcc46-pr48611.patch
While the bug is most probably elsewhere, I wonder why
note_eh_region_may_contain_throw doesn't stop propagating on ERT_MUST_NOT_THROW
regions. In my understanding no exception is ever propagated out of those
regions, the program would be terminated instead, so I wonder why we should be
trying to handle thrown exceptions in the outer regions.
The patch makes the ICE go away, as we don't needlessly try to handle
exceptions in the outer try {} finally {}.
