[ https://issues.apache.org/jira/browse/AMQCPP-452?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ] Jeffrey B closed AMQCPP-452. ---------------------------- > 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. -- This message is automatically generated by JIRA.
