Description of problem:

After cloning a managed object and then handling an exception, the process received an Access Violation while freeing the object and its clone.

Version-Release number of selected component (if applicable):

0.7.946106-12

How reproducible:

static, easy.

Steps to Reproduce:

The specific case that failed was
  request = receiver.fetch();
  address = request.ReplyTo;
  sender = session.CreateSender(address);

The bug occurs during the cloning of the Address object from the request.ReplyTo. After that line of code there are two managed objects that have pointers to the same unmanaged object. When the CreateSender function exits then the process will get an accvio during shutdown.
