Well, I'm not really sure, but I have a couple of different builds of
emacs, and when I load the emacs-zmq precompiled binaries they crash my
main emacs, which has native-compilation, but not the other emacs I
tried this in. I also get the same result of crashing native emacs, when
using the packaged build proceedure of emacs-zmq. The hidden-visibility
branch seems to fix these problems.

Can I help pinpointing the issue somehow?
