Segfault in ZeroMQ/2.1, session.cpp:152

[hintjens]

This program reproduces a segfault in 2.1: http://gist.github.com/588262

1. Start in two windows
   myname d1 d2
   myname d2 d1
2. Kill either instance
3. Other instance crashes

   Allow TCP sockets to be half-open #9 0x002b4a4e in clone () from /lib/tls/i686/cmov/libc.so.6

Trigger of crash is ZMQ_IDENTITY on sub socket; without this the code runs without crashing.

Fixed in 9d96e00. Please, check whether it works as expected now.
