Yes it should be rejected as A is a private name of A<T1> and A<T1> is priv=
ate
to B. clang rejects it for the same reason though has a better error messag=
e:
<source>:12:19: error: 'A' is a private member of 'A<T1>'
        class D : A<T2> { };
                  ^
<source>:8:11: note: constrained by implicitly private inheritance here
class B : A<T1> { };
          ^~~~~
<source>:6:7: note: member is declared here
class A { };
