--- Comment #10 from Markus Trippelsdorf <trippels at gcc dot gnu.org> ---
A bit more reduced:

markus@x4 tmp % cat test.ii
namespace poses
{
}
namespace utils
{
using namespace poses;
}
namespace poses
{
class J
{
public:
  J ();
  virtual void m_fn1 (int &p1, int);
};
class I : utils::J
{
};
class D
{
public:
  virtual void m_fn1 (poses::I &) const;
  void m_fn2 ()
  {
    I p;
    m_fn1 (p);
  }
};
class K : utils::J, public utils::D
{
};
struct F
{
  K *operator->();
};
class N : public K
{
  void m_fn1 (int &p1, int);
  void m_fn1 (I &) const {}
};
class L;
struct M
{
  L *operator->();
};
class L
{
public:
  F poseChange;
};
class G
{
  G ();
};
}

using namespace utils;
M h;
G::G () try
{
  N f;
  f.m_fn2 ();
  throw;
}

catch (int) {}

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