I will check this patch tomorrow (Jan 24th) to make sure that it fixes the
problem on non-reduced test cases.

Reduced testcase:
class Object {
  virtual Object* clone() const =0;
  virtual char* print() const;
};
class alphabet: virtual public Object{};
class Nucleotides: public alphabet {};
class DNA: public Nucleotides {
  virtual DNA* clone() const {return new DNA(*this);}
};
int main() { }
--- CUT ---
This testcase requires thunks and virtual inheritance.
