This is related to a couple of bugs that were reported last week and
have been fixed in the 3.2.x fixes branch.  You can check out a copy of
the code from here:

svn co
https://svn.apache.org/repos/asf/activemq/activemq-cpp/branches/activemq-cpp-3.2.x

These fixes will be included in the next patch release v3.2.2
