commit a67d153cc7493f918f93d2ddb9aa62a27b434e5e Author: Nick Mathewson <nickm@torproject.org> Date: Tue Jul 31 08:41:27 2018 -0400 Always call tor_free_all() when exiting tor_run_main() We would usually call it through tor_cleanup(), but in some code paths, we wouldn't. These paths would break restart-in-process, since leaving fields uncleared would cause assertion failures on restart.
