Martin Sebor <msebor at gcc dot gnu.org> changed: What |Removed |Added ---------------------------------------------------------------------------- Known to work| |12.0 --- Comment #9 from Martin Sebor <msebor at gcc dot gnu.org> --- Today's trunk doesn't reproduce it but the warning is still issued with GCC 12 for a GCC 11 translation unit, so it must be some library change that's made it go away.
