error.h again:

     * Create an error and add additional explanation:
     *     error_setg(errp, "invalid quark");
     *     error_append_hint(errp, "Valid quarks are up, down, strange, "
     *                       "charm, top, bottom.\n");
---> * This may require use of ERRP_GUARD(); more on that below.
