The following testcase asserts on mozilla-central revision 1ed5a88cd4d0 (run with --fuzzing-safe --ion-eager): function y() { return "foo,bar"; } function x() { var z = y().split(','); for (var i = 0; i < z.length; i++) {} } gczeal(2); Object.prototype.length = function () {}; x();

Actually this should be a security-bug because gczeal is involved and we're crashing after confusing some types.

Over IRC, efaust said this is probably a dupe of something he has an unlanded patch for, so I'm just going to assign it to him, and decoder's robots can confirm this, or something.

This is indeed a dupe of 906035, with the same assertion.
