> We found a crash in activemqcpp when we are shutting down the message broker.  In the
meanwhile, our application is still trying to send messages to the broker, and to receive
messages from it. Could you please take a look at this problem? Much thanks for your help!

> The place of the crash appears to be in TransportFilter::Fire(Exception&) on line
49. The content of the address that the listener pointer is pointing to seems to be corrupted/garbage.
Please see the call stack in the attached screen shot for details. 
> Attached please also find a test program to reproduce the problem. Step to run the test
program:
> (1) download and unzip test program
> (2) register GTOUD.dll
> (3) register CmsMessageHandlerCOMUD.dll
> (4) run CmsMessageHandlerCOMTest.exe
> (5) repeatedly restart activemqcpp broker. 
> (6) observe the crash
