I don't know where to send bug report of rn and I believe this bug
was reported a few months ago already in this group but failed to
show up in patches:

Version: 4.3, patchlevel 40
Output of 'v' in rn: @(#)$Header: rn.c,v 4.3.1.4 85/09/10 11:05:13 lwall Exp $

Description: When news article files have file mode 775, the program crashed with
			 an IOT trap when moving to news group mode:

panda<63 chen>% rn (and hit 'y' to enter a group)
IOT trap
panda<64 chen>% tb -l       ( Apollo's adb equivalent, sort-off )
Process        2338 (parent 1357, group 2338)
Time           89/12/18.17:04(MST)
Program        //node_9f51/usr/local/bin/rn

Cause: The order of evaluation in art.c line 107 is wrong ( '!=' has high
	   priority than '&' )

Fix: Add parentthesis around the bitwise pair before comparing:

*** art.c	Mon Dec 18 17:14:27 1989
--- art.c.orig	Mon Dec 18 17:14:04 1989
***************
*** 104,110 ****
      if (fstat(artfp->_file,&filestat))
  			    /* get article file stats */
  	return DA_CLEAN;
!     if ((filestat.st_mode & S_IFMT) != S_IFREG)
  	return DA_NORM;
      artsize = filestat.st_size;
  			    /* from that get article size */
--- 104,110 ----
