Hi, I'm pretty new to Qpid and my application includes an AP{I server listening on a Qpid connection. We did the sequence as shown in the examples (i.e., Connection connection(..); ... connection.open(); .. Receiver receiver --> connection.close(); receiver.close();) and it works fine. Problem is that in some configurations when exiting from our application, AFTER application cleanup is completed we have a Qpid exception #0 0x00007fe73311cd05 in raise () from /lib/x86_64-linux-gnu/libc.so.6 #1 0x00007fe733120a47 in abort () from /lib/x86_64-linux-gnu/libc.so.6 #2 0x00007fe7350476dd in __gnu_cxx::__verbose_terminate_handler() () from /usr/lib/x86_64-linux-gnu/libstdc++.so.6 #3 0x00007fe735045926 in ??

My guess is it is related to scope of variables holding Qpid API objects. E.g. do you have any static variables holding connection/session/receiver handles? Are you using any libraries that themselves use Qpid (and if so what is the link order)?
