--- Comment #3 from Marek Polacek <mpolacek at gcc dot gnu.org> ---
clang++ says
w.C:4:25: error: type 'A<X>' (aka 'int') cannot be used prior to '::' because
it has no members
template < typename X > A < X >::a;
                        ^
w.C:1:23: note: type alias template 'A' declared here
template < typename > using A = int;
                      ^
