       * pt.c (unify_pack_expansion): If we didn't deduce any actual
       bindings for the template parameter pack, don't try to keep the
       empty deduced arguments.
       (unify): If a parameter is a template-id whose template argument
       list contains a pack expansion that is not at the end, then we
       cannot unify against that template-id.
