--- Comment #12 from Andrew Pinski <pinskia at gcc dot gnu.org> ---
match.pd looks like it has a type bug:
/* Simplify pointer equality compares using PTA.  */
(for neeq (ne eq)
 (simplify
  (neeq @0 @1)
  (if (POINTER_TYPE_P (TREE_TYPE (@0))
       && ptrs_compare_unequal (@0, @1))
   { neeq == EQ_EXPR ? boolean_false_node : boolean_true_node; })))


It assumes all types of EQ_EXPR/NE_EXPR will be boolean_type_node which is not
true.
It should be using constant_boolean_node (neeq != EQ_EXPR, type); .
