--- Comment #2 from Jonathan Wakely <redi at gcc dot gnu.org> ---
Slightly further reduced:

struct string_view
{
  constexpr string_view(const char* p) : p(p) { }
  const char* p;
};

struct Foo {
  constexpr string_view getfoo() const {
    return {&foo};
  }
private:
  const char foo = 'c';
};

inline constexpr Foo foo;

template <typename>
struct Bar {
  static constexpr auto bar = foo.getfoo();
};

auto& baz = Bar<int>::bar;
