Really? I don't see how the OPs code is any different in this regard. To 
quote the OP:

</OP>

How does catcher find out what exception was thrown? It seems it must 
use the same idiom that ::HandleException() uses, i.e. throw; inside a 
try block. Once you do that, most debuggers won't be able to show the 
original stack trace.
