I suspect this may be the same crash that caused us to disable it in #1758. It was reintroduced in pyzmq 26 due to the new build system and libzmq 4.3.5 appears to not have fixed the error.
It is my hope that this will fix #1981, which I suspect was caused by re-enabling IPC. Maybe someday the upstream bug in libzmq can be understood and fixed.
update: I've confirmed this fixes at least one Windows system with no other practical workaround, which is enough for me.
