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.
