Subject [jira] Created: (AMQCPP-180) Segmentation fault after removing derivation from runnable
Date Wed, 04 Jun 2008 09:45:00 GMT
Segmentation fault after removing derivation from runnable

                 Key: AMQCPP-180
             Project: ActiveMQ C++ Client
          Issue Type: Bug
          Components: Example Code
    Affects Versions: 2.1.3
         Environment: #CentOS release 5 (Final)
Linux orion 2.6.18-53.el5 #1 SMP Mon Nov 12 02:14:55 EST 2007 x86_64 x86_64 x86_64 GNU/Linux

            Reporter: Wolfgang.Klein

            Priority: Minor

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
Starting the example:
Sent message #1 from thread -1420801584
No valid response received for command: (null), check broker.

        FILE: activemq/core/ActiveMQProducer.cpp, LINE: 149
        FILE: activemq/core/ActiveMQProducer.cpp, LINE: 108
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).

Starting the example:
Sent message #1 from thread
Segmentation fault

WHY ???????????????
