--- Comment #1 from Richard Biener <rguenth at gcc dot gnu.org> ---
It might also fail on the GCC 14 branch when checking is enabled since this=
 is

  // We sometimes get compatible types copied from operands, make sure
  // the correct type is being returned.
  if (name && TREE_TYPE (name) !=3D r.type ())=20
    {
      gcc_checking_assert (range_compatible_p (r.type (), TREE_TYPE (name))=
);
