--- Comment #4 from Yusuke Suzuki <ysuzuki at apple.com> ---
No, the current behavior of JSC is correct in terms of the spec.
When non-iterable object comes to Promise.race, we should return rejected promise, not throwing a type error.


3. Let iteratorRecord be GetIterator(iterable).
4. IfAbruptRejectPromise(iteratorRecord, promiseCapability).

And JSC returns rejected promise from Promise.race.

$ Promise.race({}).catch(function (error) { print(error); });
[object Promise]
TypeError: undefined is not a function
