It's exactly the same as Bug 30542 and Bug 30575. I'd guess it is really a
duplicate of Bug 22456, and the "dead" code is indeed dead but not in the sense
we think it is. A single comment from gcc developers would clarify it,
something like "We are indeed aware of this serious bug and #22456 is just an
umbreall bug which happened to have bogus test case" or "No, it's not a serious
bug, and the code there and here is the same". Or something.
