Weird. Can you print the value of self->actor in zyre.c, after _new
and inside _destroy, to make sure it's not been changed?

Without the destroy you'll get the dangling socket errors.

The code looks correct, I don't see any issue with it. Since you can
reproduce the error, the thing to do is establish at what point the
actor tag gets corrupted, or the actor reference (self->actor in the
zyre object) gets corrupted.
