AFAIU, it says that Emacs was _loading_ rng-loc.  That doesn't mean
the problem is in rng-loc's code.  The fatal signal comes from the
maxOS implementation of dlopen, so I suspect that the way we restart
Emacs messes up some OS data structures regarding loaded shared
libraries or something.

Note that the previous crash you posted also crashes inside dlopen.

So I think it's safe to say that restarting Emacs makes loading of
*.eln files (and maybe share libraries in general) fragile and tending
to crash, for some reason.  Maybe we should explicitly unload all the
*.eln files when we restart?
