--- Comment #4 from Jason Merrill <jason at gcc dot gnu.org> --- (In reply to Alexander Monakov from comment #3) > -fabi-version=12 is not documented, not mentioned in release notes, and not > wired up in -Wabi. -Wabi=11 warns about this. With an incorrect message, since this is a bug. I'll also fix the documentation.
