--- Comment #3 from Peter Cordes <peter at cordes dot ca> --- (In reply to Jonathan Wakely from comment #2) > You've reported this against libstdc++ I had to take a guess at the right component, based on a couple other std::atomic bugs I looked at. Apparently I picked wrong, if libstdc++ really is just the headers and not compiler internals at all. Can someone please mark the appropriate component? I mostly just look at compiler asm output, not the real internals.
