Could you provide the C++ code? Also what platform and compiler?

using ActiveMQ 4.1.1 and 5.0 on Red Hat Linux with the same exception.
I have started ActiveMQ succesfully and connect to

the queue creation of TEST.FOO, I get the following exception in the
ActiveMQ console window (using 5.0):

The port number in the above trace is 49120 but this varies between
runs of
ActiveMQ.
The executing C++ reports the following exception:
free(): invalid pointer 0xb54ca26c!
response from futureResponse was invalid

I'm not sure what is causing this issue. Any help would be appreciated.
