--- Comment #3 from Drea Pinski <pinskia at gcc dot gnu.org> --- The big question is what is the C standard requirement here for memchr, is it that all of the array from 0...size needs to be valid or not? I think the standard does say that and requires that. So in theory memchr could find the first occurrence and still read up to size too.
