     38 * SUMMARY: Regression test for bug 108440
     39 * See http://bugzilla.mozilla.org/show_bug.cgi?id=108440
     40 *
     41 * We shouldn't crash trying to add an array as an element of itself (!)
     42 *
     43 * Brendan: "...it appears that Array.prototype.toString is unsafe,
     44 * and what's more, ECMA-262 Edition 3 has no helpful words about
     45 * avoiding recursive death on a cycle."
