actionscript 3 - Error.getStackTrace() returns a string unparseable in flashdevelop? -

accessing string created error's getstacktrace function resulting in unusual behaviour in flashdevelop ide.

package {     import flash.display.sprite;      public class main extends sprite     {         public function main():void         {             print("start");              var err:error = new error();             var stack:string = err.getstacktrace();              print(stack);             // occurs when replaced stack.length or stack[0]              print("end");         }          private function print(input:*):void         {             trace(input);             trace("---");         }     } } 

when run in flash cs4 outputs

start --- error     @ main() --- end --- 

but when run in flashdevelop (replacing trace() flashconnect.trace()) outputs

start --- 

is bug, or flashdevelop handling errors in different way intentionally?

if latter there workaround access stacktrace of error?

i managed fix switching using dubugging version of flash player, hope helps else problem.
