Hello,
using that page as guide:
http://help.adobe.com/en_US/FlashPlatform/beta/reference/actionscript/3/flash/events/Uncau ghtErrorEvent.html#includeExamplesSummary
(last sample on where to insert handlers) what about:
<s:SWFLoader id="swfLoader" init="swfLoaderInitHandler(event)" source="B.swf"/>
and:
protected function swfLoaderInitHandler(event:Event):void
     if(!swfLoader.content) return;
     swfLoader.content.loaderInfo.uncaughtErrorEvents.addEventListener(UncaughtErrorEvent.UNCAU GHT_ERROR,
          uncaughtErrorHandler);
protected function uncaughtErrorHandler(errorEvent:UncaughtErrorEvent):void
     if(errorEvent.error is Error)
          var e:Error = errorEvent.error as Error;
          // my error is 1009 - it is expected here
          const NULL_ERROR:uint = 1009;
          if(e.errorID == NULL_ERROR)
               errorEvent.preventDefault();
               Alert.show(e.errorID+" "+e.message);
          // else fall through
     // else fall through
B is supposed to fail:
private var emptyObject:Object = null;
public function B()
     flash.utils.setTimeout(throwErrorNow, 100);
protected function throwErrorNow():void
     emptyObject.numericValue();
