[Bug tree-optimization/44861] internal compiler error: in vectorizable_load, at tree-vect-stmts.c:3812

------- Comment #1 from irar at il dot ibm dot com  2010-07-08 09:14 -------
The failure is in vectorizable_store():

          /* If accesses through a pointer to vectype do not alias the original
             memory reference we have a problem.  This should never happen.  */
          gcc_assert (alias_sets_conflict_p (get_alias_set (data_ref),
                      get_alias_set (gimple_assign_lhs (stmt))));


Since MEM_REF merge the types struct Foo * and struct counted_base * pass
types_compatible_p() test in vect_check_interleaving(). But in revision 161655
(the merge) the basic block gets vectorized and there is no ICE.
