--- Comment #1 from Marc Glisse <glisse at gcc dot gnu.org> --- (I thought we already had a PR or 2 about this) The future is likely to be based on http://www.open-std.org/jtc1/sc22/wg21/docs/papers/2015/p0035r0.html but sadly this is moving forward quite slowly. Users can override the global operator new, so we have no way (unless -fwhole-program or -flto) to know if this alignment is handled or not. This of course does not prevent from having a warning that people can chose to enable/disable.
