        * stor-layout.c (layout_type): Assert that aggregates do not
        have their alias sets set.
        * alias.c (get_alias_set): Return alias set zero for incomplete
        types, return the alias set of the element for incomplete array
        types, but do not remember these.

        * gfortran.dg/pr32921.f: New testcase.
