Thanks for picking up the investigation.  Does that mean that the above
fix was partial and that there likely is a use after free somewhere
else?

It's good at least that this ZMQ_ROUTER_MANDATORY option catches that.

(Also, these scary Btrfs errors are a reminder that the file system got
corrupted at some point and should be recreated at some point -- I hope
they are not related to the problem at hand but we should keep an eye on
things).
