On 3.4 branch and mainline the invalid default parameter is only
diagnosed at instantiation time and not at definition time:

======================================
template<typename> struct A {};

template<typename T> struct B
{
    A<T> a;

    void foo(A<T>* = &a);

    void bar() { foo(); }
};

// template struct B<int>;
======================================

On the 3.3 branch we get the error message already at defintion time:

bug.cc:7: error: invalid use of member `B<T>::a'
