--- Comment #8 from Jonathan Wakely <redi at gcc dot gnu.org> ---
Like I already suggested in comment 3:

Either the overloads should conflict because of [over.load]/2.3 (and the
definition of Derived should be ill-formed) or they should be hidden and not
visible in Derived (so the call to test.method() should be ill-formed).
