--- Comment #1 from Martin Li=C5=A1ka <marxin at gcc dot gnu.org> ---
Started with r9-6405-gbddee796d0b4800b.

Reduced test-case:

  _Predicate _M_pred;
  template <typename _Iterator> void operator()(_Iterator __it) {
    _M_pred(__it);

};
template <typename _Predicate> _Iter_pred<_Predicate> __pred_iter(_Predicat=
