Eric Gallager <egallager at gcc dot gnu.org> changed: What |Removed |Added ---------------------------------------------------------------------------- Status|NEW |RESOLVED Resolution|--- |INVALID --- Comment #3 from Eric Gallager <egallager at gcc dot gnu.org> --- (In reply to Eric Gallager from comment #2) > Comment in builtins.def says: > > /* bcmp, bcopy and bzero have traditionally accepted NULL pointers > when the length parameter is zero, so don't apply attribute "nonnull". */ > > svn blame says Kaveh Ghazi wrote that comment; cc-ing him I'm thinking that this comment means that the current behavior is intentional, in which case there's no bug here.
