This particular file does not crash for me on Windows, but I have a similar crash when linking another character blend file and File > New leads to the crash. Really hope it can be be fixed for the final 2.8 release, thanks for your work.

Noticed that if you link the rig, make the proxy, then save the file as a new scene, the new scene when loaded will NOT crash on File > New. So it seems to only happen when the proxy is made in the same session.

Don't know if that clears or muddies things up

Confirmed, seems to be a double-free of the bbone cache (or maybe whole armature posebone cache?), that one probably end up being shared by both linked object and its proxy.

Will check further tomorrow.
