--- Comment #1 from Jakub Jelinek <jakub at gcc dot gnu.org> ---
Started with r12-5835-g0ab29cf0bb68960c1f87405f14b4fb2109254e2f
I guess the
                  if (c_parser_next_token_is (parser, CPP_DEREF))
                    t =3D build_simple_mem_ref (t);
is wrong, CPP_DEREF handling elsewhere calls
          expr =3D convert_lvalue_to_rvalue (expr_loc, expr, true, false);
and uses
          expr.value =3D build_component_ref (op_loc,
                                            build_indirect_ref (op_loc,
                                                                expr.value,
                                                                RO_ARROW),
                                            ident, comp_loc);
So I think we should do that convert_lvalue_to_rvalue and build_indirect_ref
instead of build_simple_mem_ref.=
