[zeromq-dev] assertion failed in zmq::context_t::~context_t()

[Ilja Golshtein]

Hello.

Application http://pastebin.com/8MRQauSq
more or less reliably crashes
with following backtrace

(gdb) bt
#0  0x00002b37406c42c5 in raise () from /lib64/libc.so.6
#1  0x00002b37406c5d70 in abort () from /lib64/libc.so.6

#4  0x0000000000401464 in main ()
    at /home/ilya_golshtein/projects/zeromq-play/homicide.cpp:45


if compiled with NDEBUG.

The issue is obvious and caused by this code

        inline ~context_t ()
        {
            if (ptr == NULL)
                return;
            int rc = zmq_term (ptr);
            ZMQ_ASSERT (rc == 0);
        }

According to manual, zmq_term can return non-zero in certain legitimate conditions,
and I don't quite understand why we assert that it is zero.

This is about 2.2.0, while 2.2.2, at first glance, is affected as well.

Should I provide patches?

Thanks.
