 A simpler testcase is this:
 ---------------------------
 template <class T>
 struct X {
   template <class U> void operator+=(U);
 
   template <class V>
   template <class U>
   friend void X<V>::operator+=(U);
 };
 
 int main() {   
   X<int>() += 1.0;
 }
 --------------------------
 
 It ICEs in retrieve_specialization, in 3.2, 3.3 and mainline. The ICE goes 
 away if the befriended function is not an operator, or if in the one line 
 in main I call
   X<int>().operator+= (1.0)
 instead.
