Andrew Pinski <pinskia at gcc dot gnu.org> changed: What |Removed |Added ---------------------------------------------------------------------------- Status|UNCONFIRMED |RESOLVED Resolution|--- |INVALID --- Comment #1 from Andrew Pinski <pinskia at gcc dot gnu.org> --- There is a redzone for the variables but there is no way it going to be this large. In this case, it just happens that cc[204-172][0][0][0][0] points into the variable dd and therefore is a valid address.
