        * call.c (convert_arg_to_ellipsis): Instead of cp_build_addr_expr
        build ADDR_EXPR with REFERENCE_TYPE.
        (build_over_call): For purposes of check_function_arguments, if
        argarray[j] is ADDR_EXPR with REFERENCE_TYPE created above, use
        its operand rather than the argument itself.

        * g++.dg/warn/Wformat-2.C: New test.
