valid AS3 will crash iPhone app on startup

Steps to reproduce:

1. Add this code to a Flex Mobile Project:

        public class Foo extends EventDispatcher {
             public override function addEventListener(type:String,  listener:Function, useCapture:Boolean=false, priority:int=0,  useWeakReference:Boolean=false):void {
                 var thisFunc:Function= arguments.callee;
                 super.addEventListener(type, listener, useCapture, priority, useWeakReference);
             }
         }

2. Refer to the class Foo somewhere in the application, for example the creation complete handler of MainHomeView.mxml:

        protected function view1_creationCompleteHandler(event:FlexEvent):void {
             var foo:Foo;
         }

3. Debug this on an iOS device using the 'Standard' packaging method.  Also, you could export a Release build for iOS.

When the iOS app launches, it will crash before running any code  written by the programmer-- just the *presence* of this code in the app  causes it to crash (!).  I'm attaching a crash log.

I've filed a bug for this here: https://bugs.adobe.com/jira/browse/FB-32130
