--- Comment #4 from Andrew Pinski <pinskia at gcc dot gnu.org> ---
Confirmed.

                      /* After the optimization PHI result can have value
                         which it couldn't have previously.  */
                      int_range_max r;
                      if (get_global_range_query ()->range_of_expr (r, phires,
                                                                    phi))


Yes int_range_max here is almost definitely wrong for pointer types.
