ZMQ::FFI uses a fixed size (40) memptr for zmq_msg_t

The tests for this module core dump against the latest development version of libzmq.
Please look into it.

It looks like the size of the zmq_msg_t struct recently changed in the dev repo. I'll look into a way of generating this value instead of hard coding it.

ok this should be resolved on master, so let me know if you still experience problems. I now generate zmq_msg_t size by using the headers of all the zeromq versions including dev. I use 2x the largest size among all versions, which should provide sufficient wiggle room between ZMQ::FFI releases and regenerations of the size constant.

I've added tests against the libzmq dev version in addition to stable, and have requested daily travis builds at https://traviscron.pythonanywhere.com. So any future explosions caused by changes in libzmq dev should be noticed immediately.

Thanks for the report!

Thanks for the quick turnaround! Works like a charm..
