--- Comment #15 from Markus Trippelsdorf <trippels at gcc dot gnu.org> ---
So, what about (crashes trunk and 4.8.3) :

class J
{
public:
  J ();
  virtual void m_fn1 (int &p1, int);
};
template <class TDATA> class D
{
public:
  virtual void m_fn1 (TDATA &) const;
  void m_fn2 ()
  {
    TDATA p;
    m_fn1 (p);
  }
};

class I : J
{
};
class K : J, public D<I>
{
};
struct F
{
  K *operator->();
};
class N : public K
{
  void m_fn1 (int &p1, int);
  I mean;
  void m_fn1 (I &) const {}
};
class L;
struct M : F
{
  L *operator->();
};
class L : J
{
public:
  F poseChange;
};
class G
{
  G ();
};
M h;
G::G () try
{
  N f;
  f.m_fn2 ();
  throw;
}

catch (int) {}

void fn1 () { h->poseChange->m_fn2 (); }
