Major Description
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:
(gdb) bt

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.
