[jira] [Closed] (AMQCPP-544) decaf Lock::lock() triggering ABRT within destructors

["Timothy Bish (JIRA)" <ji...@apache.org>]

     [ https://issues.apache.org/jira/browse/AMQCPP-544?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]

Timothy Bish closed AMQCPP-544.
-------------------------------
    Resolution: Cannot Reproduce

Have not seen this in testing the code that will become v3.9.0.  Perhaps a problem that has been resolved by another fix.

> We are experiencing SIGABRTs during attempts to disconnect a client from the broker by calling the destructor of ActiveMQConnection.
> Here's the portion of the stack trace that includes activemq-cpp code:

> The call to {{__cxa_pure_virtual()}} in frame 9 indicates that {{decaf::util::concurrent::Lock::lock()}} is calling a pure virtual function. Since this is happening within destructor calls (of both ActiveMQConnection and ConnectionConfig), it has evidently triggered std::terminate from libstdc++, and hence the abort.
