Timothy Bish commented on AMQCPP-452:
-------------------------------------
Since the Thread is created on the stack its lifetime is for the duration of
main and therefore is destroyed after the shutdownLibrary method has been
called. The thread needs the library resources which are destroyed and that's
why it fails.
place you thread in its own scope like so:
{code}
{
Thread HBthread(hbc);
HBthread.start();
HBthread.join();
//sleep(3);
delete hbc;
}
{code}
> Shutdown causing core dump in 3.5.0
> -----------------------------------
>
> Key: AMQCPP-452
> URL: https://issues.apache.org/jira/browse/AMQCPP-452
> Project: ActiveMQ C++ Client
> Issue Type: Bug
> Components: Decaf
> Affects Versions: 3.5.0
> Environment: HPUX 11.31
> Reporter: Jeffrey B
> Assignee: Timothy Bish
> Priority: Critical
> Labels: shutdown, thread
> Attachments: amqsms.cpp
>
> Original Estimate: 24h
> Remaining Estimate: 24h
>
> Whenever a thread is created in my receiver program, The use of the
> activemq::library::ActiveMQCPP::shutdownLibrary(); causes a core dump after
> my return 0; statement
> It does not happen on my sender after applying patch for a similar issue, and
> this is almost identical, so I can not find the difference.
> The cause is trying to lock a null mutex in the function
> Threading.cpp::attachToCurrentThread(). This gets called only once in my
> sender program, during the
> activemq::library::ActiveMQCPP::initializeLibrary(); call, but it gets called
> twice in my receiver program, once in the same place and then after the
> return 0; line. At that point library->globalLock is NULL.
> Will attach my source in a moment, but I have literally taken it down to the
> bare minimum so that it has no function.
