--- Comment #7 from [email protected] --- A commit references this bug: Author: kib Date: Thu Dec 17 19:51:39 UTC 2020 New revision: 368735 URL: https://svnweb.freebsd.org/changeset/base/368735 Log: Fix a race in tty_signal_sessleader() with unlocked read of s_leader. Since we do not own the session lock, a parallel killjobc() might reset s_leader to NULL after we checked it. Read s_leader only once and ensure that compiler is not allowed to reload. While there, make access to t_session somewhat more pretty by using local variable.
