re PR c++/13387 (assignment to base class corrupts subclass)
cp:
PR c++/13387
* class.c (finish_struct_1): Compute mode and alias set for
CLASSTYPE_AS_BASE.
* call.c (build_over_call): Use CLASSTYPE_AS_BASE for trivial
assignment of a class, as necessary.
* cp-lang.c (cxx_get_alias_set): The alias set as a base is the
same as for the complete type.
testsuite:
PR c++/13387
* g++.dg/expr/assign1.C: New test.
