A fix for this bug was reported recently by Bob Weissman <bob@omni.com>.
Here is the message that he sent me:

Subject: Smail3 bug found and fixed

For many months, I've been having big pains figuring out why I
would intermittently get paniclog entries which read:

  04/29/91 17:14:01: /var/lib/smail/directors: 
  04/29/91 17:20:19: [m0jXiS2-0004o4C] /var/lib/smail/directors: 
  04/29/91 17:20:20: [m0jXiS4-0004o7C] /var/lib/smail/directors: 
  04/29/91 17:20:21: [m0jXiS5-0004o8C] /var/lib/smail/directors: 
  04/29/91 17:20:22: [m0jXiS6-0004o9a] /var/lib/smail/directors: 
  04/29/91 17:20:24: [m0jXiS7-0004oAC] /var/lib/smail/directors: 
  04/29/91 17:20:25: [m0jXiS8-0004oFC] /var/lib/smail/directors: 
  04/29/91 17:20:26: [m0jXiS9-0004oGC] /var/lib/smail/directors: 
  04/29/91 17:27:03: /var/lib/smail/directors: 
  04/29/91 17:27:04: [m0jXiYZ-0004oIC] /var/lib/smail/directors: 
  04/29/91 17:30:23: /var/lib/smail/directors: 

ad nauseam.

I think I finally found the problem today after rebuilding smail with
debugging enabled.  There are several routines in directors/include.c
which return char* but have no return statements in their bodies.  I
was falling victim to random return values.

My include.c carried an SCCS id of "@(#)include.c 3.19 3/17/89 17:18:25".
Diffs follow.
