* Version WebKit nightly r188633 * SUMMARY Executing a named IIFE function that uses ES6 default parameters in the console causes a crash. * STEPS TO REPRODUCE 1. Open Console 2. Execute the following snippet (function fn(oo = 'test') { console.log(oo); })() => Crashes the Browser * EXPECTATION Console prints "test" Interestingly an anonymous function works: (function(oo = 'test') { console.log(oo); })()
