--- Comment #1 from Martin Liška <marxin at gcc dot gnu.org> ---
Started with r11-6800-g29853c653245c37e, reduced test-case:

$ cat pr100502.ii
template <class> struct EnumeratorRange {
  struct Iterator {
    EnumeratorRange *range_;
    friend auto operator==(Iterator, Iterator i) { i.range_->end_reached_ }
  };

private:
  bool end_reached_;
};
