commit 5ecd1fec1583b8aa865ac5cae0cece42451395bd
Author: Nick Mathewson <nickm at torproject.org>
Date: Wed Jun 20 13:02:05 2018 -0400
Move horrible-emergency handling into torerr.[ch]
Previously we had code like this for bad things happening from
signal handlers, but it makes sense to use the same logic to handle
cases when something is happening at a level too low for log.c to be
involved.
My raw_assert*() stuff now uses this code.
