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