Note that failing with large bounds is questionable (there is an apparent conflict between ISO C, where passing a large bound seems valid, and POSIX, where large bounds require errors; see <http://austingroupbugs.net/view.php?id=761>; I'm not sure if any liaison issue for this ever got passed to WG14). -- Joseph S.
