Andrew Pinski <pinskia at gcc dot gnu.org> changed: What |Removed |Added ---------------------------------------------------------------------------- Status|UNCONFIRMED |RESOLVED Resolution|--- |INVALID --- Comment #6 from Andrew Pinski <pinskia at gcc dot gnu.org> --- Note even though the length that is passed to memcpy is zero, the arguments have to be non-null. So adding the check around the call to memcpy should fix the issue.
