This is what remains from PR 10394 after Giovanni's analysis.
I'll close 10394 once this has a PR number.

The following piece of code gives an ICE with 3.4.

 template <class T>
 struct A
 { 
   template <class U>
   class B {};
 };
  
 template <class V>
 struct C
 { 
   C()
   {
       A<typename V::X>::template B<int> k;
   }
 };
 
 struct E
 {
   typedef int X;
 };
 
 template struct C<E>;
 
 int main()
 {}
