Bug 241953 – [JSC] Generic iterator protocol function should be invisible to Function's caller getter

• Status: RESOLVED
• Resolution: FIXED
• Component: JavaScriptCore

This code should have returned function foo instead of null

function foo(arr) {
    return [...arr];
}

let obj = {};
obj[Symbol.iterator] = function bar () {
    alert(arguments.callee.caller);
    return {
        next() { return { done: true }; }
    };
};
foo(obj);
