Summary for-in over object with a Symbol key breaks upon JITing

See http://jsbin.com/pelokucuwe/1/edit?js,console Console shows that iterating over an object with a Symbol key breaks over time (theory is due to JITing). Observed: ["bar", function bar() {}] ["bar", 1] Expected: ["bar", function bar() {}] ["bar", function bar() {}] From https://github.com/emberjs/ember.js/issues/13796
