[Bug c++/77742] Warning about placement new for over-aligned type
https://gcc.gnu.org/bugzilla/show_bug.cgi?id=77742 --- Comment #1 from Richard Biener --- As placement new has no control over the memory alignment the warning looks useless to me. In this particular case we even know statically the memory is well-aligned.
