If tmux causes a kernel panic it is entirely certain it isn't a tmux problem, it is a kernel bug.
The message you show only really shows it is something to do with the VFS but not much else. specfs is basically a set of utility routines used by a whole bunch of other stuff. Are you certain you can't reproduce it without tmux? Whether you can or not, you need to talk to Apple or whoever is responsible for the kernel. I don't use OS X and of course it is closed so even if you give more information I can't do much here :-).
