* 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."
