Slightly more reduced testcase for -O2 -g:
template <typename>
class A;
template <class>
struct B;
template <typename T, typename = B <T>, typename = A <T> >
class C;
template <typename _Tp>
class A {};
template <typename T, typename, typename U>
struct D
{
  struct E
  {
    T *e1 () {}
    void e2 (U a) { e3 (a); }
    void e3 (U) throw ();
  };
  struct F { F (T *, U) {} };
  F f;
  E *d1 () {}
  static E & d2 () {}
  D () : f (d2 ().e1 (), U ())
  {
    d1 ()->e2 (this->d3 ());
  }
  U d3 () {}
};
template <typename, typename>
struct G
{
  virtual ~G () {}
};
template <typename T, typename U>
struct H
{
  void h1 (G <T, U> *);
};
template <typename T, typename U>
struct I : H <T, U>
{
  I () { this->h1 (0); }
};
template <typename T, typename U, typename V>
struct J : G <T, U>
{
  D <T, U, V> j;
};
template <typename T, typename U, typename V>
struct C : I <T, U>
{
  J <T, U, V> c;
};
struct K;
template <typename T, class U>
I <T, U>
& operator <<(I <T, U> &, const K &)
{
  C <U> s;
}
template I <wchar_t, B <wchar_t> >
& operator <<(I <wchar_t, B <wchar_t> >&, const K &);
