--- Comment #3 from Jakub Jelinek <jakub at gcc dot gnu.org> ---
Reduced testcase:
constexpr bool
foo (const int *x, const int *y)
{
  if (__builtin_constant_p (x < y))
    return x < y;
  return (__UINTPTR_TYPE__) x < (__UINTPTR_TYPE__) y;
}

void
bar ()
{
  constexpr int x = 0;
  static_assert (!(&x < &x));
  static_assert (!foo (&x, &x));
}

constexpr void
baz ()
{
  constexpr int x = 0;
  static_assert (!(&x < &x));
  static_assert (!foo (&x, &x));
}
