--- Comment #11 from Eric Gallager <egallager at gcc dot gnu.org> --- (In reply to Marc Glisse from comment #10) > IMO -Wmaybe-uninitialized should not be enabled by -Wall, whatever the > optimization level (even at -O3), it has too many false positives that are > all but impossible to work around (thus violating the definition of -Wall), > -Wextra is good enough for it. We could keep -Wuninitialized though (it > requires changing the dependency between these 2 warnings). I think I remember at least 1 other bug where we came to this conclusion; I forget its number right now though...
