confirmed

if Y::f is not a template then access checking succeeds

here's a C++03 version, which fails in the same way:

class X
{
    int value ;
    friend class Y ;
} ;

template <int> struct Int { };

class Y
{
public :
    template < typename T >
    static Int<sizeof(T::value)> f(T t)
    {
        return Int<sizeof(t.value)>();
    }
} ;

int main()
{
    X x ;
    Y::f(x) ; // gcc issues error
}
