State-Changed-Why:
    Confirmed. A slightly reduced testcase is this
    ----------------------------------
    struct X { int i; };
    
    template <class T> struct Y {
        typedef int X::*b;
        operator b();
    };
    
    template <class T> Y<T>::operator typename Y<T>::b() {
        return &X::i;
    }
    -------------------------------------
