        * tree-ssa-structalias.c (find_func_aliases_for_call): Use
        aggregate_value_p to determine if a function result is
        returned by reference.
        (ipa_pta_execute): Functions having their address taken are
        not automatically nonlocal.

        * g++.dg/ipa/ipa-pta-2.C: New testcase.
        * gcc.dg/ipa/ipa-pta-1.c: Adjust.
