        <pre>Clang forbids base-class destructor calls on derived objects, except when the
base is named by a template-id or a qualified-id.

template< typename >
struct b { ~ b () {} };
typedef b< int > q;

struct a : q {};

int main() {
    a x;
    x.~b< int >(); // Allowed
    x.q::~q(); // Allowed
    x.~q(); // Error
}

Also, what standard rule is being diagnosed? [class.dtor]/14 says, "The
invocation of a destructor is subject to the usual rules for member functions…"
and the example there has similar cases of base-destructor invocation, which
Clang does allow, one of which uses a qualified-id.</pre>
