// { dg-do compile }

template<typename T> struct A;
template<typename T> struct B {};
template<typename T> A<T>& operator<<(A<T>&, const B<T>&);

template<typename T>
struct A
{
  A<T>& operator<<(A<T>& (*)(A<T>&));
};

template<typename T> A<T>& foo(A<T>&);
extern A<char> c;

int
main()
{
  c << (1, foo);
}

ICEs in resolve_overloaded_unification with 3.4, 4.1.2 and the trunk, compiles
fine with 3.2.3.
