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

Reduced test-case:

$ cat pr97582.ii
template <typename, typename> class __normal_iterator {};
template <typename _Iterator, typename _Container>
void operator==(__normal_iterator<_Iterator, _Container>,
                __normal_iterator<_Iterator, _Container>);
template <typename _Predicate> struct _Iter_pred {
  _Predicate _M_pred;
  template <typename _Iterator> void operator()(_Iterator __it) {
    _M_pred(__it);
  }
};
template <typename _Predicate> _Iter_pred<_Predicate> __pred_iter(_Predicate)
{}
template <typename _RandomAccessIterator, typename _Predicate>
void __find_if(_RandomAccessIterator __first, _Predicate __pred) {
  __pred(__first);
}
template <typename _InputIterator, typename _Predicate>
void none_of(_InputIterator __last, _Predicate __pred) {
  find_if(__last, __pred);
}
template <typename _InputIterator, typename _Predicate>
void any_of(_InputIterator, _InputIterator __last, _Predicate __pred) {
  none_of(__last, __pred);
}
template <typename _InputIterator, typename _Tp>
_InputIterator find(_InputIterator, _Tp);
template <typename _InputIterator, typename _Predicate>
void find_if(_InputIterator __last, _Predicate __pred) {
  _Iter_pred __trans_tmp_1 = __pred_iter(__pred);
  __find_if(__last, __trans_tmp_1);
}
class C2 {
  void operator==(C2);
};
class C6 {
  void operator==(C6);
};
class C5 : C6, C2 {
