Looks like you are right, and it's been over-reduced.

The error being that typeof(x->value) is A, not F, right?

If so, this corrected test case still triggers ICE:


class A
{
    virtual int String ();
};

class F: public A { };

template < typename V > class G
{
    V value;
};

class D
{
    template < int N > void Verify() {
      G<F>* x = 0;
      F& name = x->value;
      name.String();
    }
};
