Description

I have unstalled ActiveMQ 5.1.0 and activemq-cpp-2.1.3.
I have used simple_producer and simple_async_consumer successful.
Then i have started several times simple_producer without starting a consumer. Which (clearly) results in an exception:

[wok@orion] ~/src 679$ /opt/apache-activemq-5.1.0/bin/simple_producer

Finished with the example.

That's all ok.

But then i haved change the SimpleProducer in line 43 and 110 to be closer to our integration:
< class SimpleProducer /: public Runnable/ {
string threadIdStr; // = Integer::toString( Thread::getId() );

I repeated the test and got a Segmentation fault (wihout a core file).
