Yes, a bug report for GCC should be opened as well. @collares do you want to take that?

Reverting to the previous behavior is safe for clang to do in any case, and thus I think we ought to. Subsequently landing a change that restricts the alignment assumptions based on allocation size would be fine, as well. But reverting the incorrect change doesn't need to wait for that to be written, and neither need wait for a discussion with GCC.
