>How-To-Repeat:
	Here's a quite small file which causes the error:
------------

{
};

template<typename Oper>
class Vakioeval
{
public:
  typedef void (*Evalf)(const Vakio&, const Vakio&);
  template<typename Vasen, typename Oikea, Evalf evalf, bool VAIHDANNAINEN>
  static void rekisteroi();
};

class Kerto
{
};


template<typename Arvo>
class Lukuvakio
{
};

template<typename Arvo>
class Kertoeval : Vakioeval<Kerto>
{
public:

  Kertoeval();
private:
  static Kertoeval rekisteroija_;

  static void pluslukuvakio(Vakio& vasen, Vakio& oikea);
};

template<typename Arvo>
Kertoeval<Arvo>::Kertoeval() : Vakioeval<Kerto>()
{
  void (*f)() = rekisteroi<Lukuvakio<Arvo>, Lukuvakio<Arvo>, pluslukuvakio, false>;
  f();

}

template<typename Arvo>
