Simple AS3 code that causes 10.2 to crash

Question

Very simple code that causes flash 10.2 to crash on all platforms.

               import mx.controls.Alert;
               private function crash(type:int, ...additionalArgs):void {
                    var msg:String;
                    switch (type) {
                         case 1: msg = "Crashes!"; break;
                         case 2: msg = additionalArgs[0]; break;
                    Alert.show("Crash : " + msg);
               private function notCrash(type:int, ...additionalArgs):void {
                    // Does nothing at all, but stops the crash....
                    if (additionalArgs) {}
                    var msg:String;
                    switch (type) {
                         case 1:msg = "Not crash"; break;
                         case 2: msg = additionalArgs[0]; break;
                    Alert.show("NotCrash : " + msg);
          ]]>

     <s:Button label="Does not crash flash" click="notCrash(2,'value')" x="10" y="10"/><s:Button label="Crash flash" click="crash(2,'value')" x="150" y="10"/>

Hi Hitomi
Thank you! Finally someone is looking into this.
I have also submitted a bug report on your site about this issues.
Currently for the developers there is a simple workaround; which is to wrap the switch statement that uses a rest parameter in a try/catch. This
prevents the crash even though the catch statement is reached!
I have also have another forum post that goes into more detail about this :
