--- Comment #2 from Jakub Jelinek  ---
The problem is that we have a type (complex double) where
TYPE_CANONICAL (TYPE_MAIN_VARIANT (t)) != TYPE_MAIN_VARIANT (TYPE_CANONICAL
(TYPE_MAIN_VARIANT (t)))
which get_alias_set code asserts on, because it does:
  t = TYPE_MAIN_VARIANT (t);
...
  if (TYPE_STRUCTURAL_EQUALITY_P (t))
...
  else
t = TYPE_CANONICAL (t);
  gcc_checking_assert (t == TYPE_MAIN_VARIANT (t));

Nathan, can you please have a look?
