Odd crash on Mac OS X with ZeroMQ 4.0.6

[Kentzo]

This is an odd crash that happens sporadically:

I've seen it multiple times, stack trace was the same. However I didn?t find any reproducible patter before it happens.

Our application is cross-platform (Linux, Windows, OSX) but we never seen anything like that on other platforms.

Please report such issues against libzmq master, thanks.
