	Subject: 4.2 csh signal related bug

	        I have on occasion run across what I believe to be a  bug
	in  4.2  csh.  The  symptoms are that when you type a command and
	hit return it starts up the program but  immediately  blurbs  out
	some message about "Reset pgrp from # to #" and sends a Hangup to
	the process.  Once this occurs you are  hosed  although  you  can
	sometimes  get a few things to run (ie, you can type ls and 1 out
	of 5 times it runs without the Reset message).
	
	As near as I can tell, this behaviour occurs just  around  either
	having  just typed ^Z or my interrupt character which leads me to
	believe it may be a signal related problem.  Two  questions,  why 
	does  this  only  happen to me (nobody else here has seen it) and
	what is it?
	
I have observed this under 4.1 csh also.  The following erroneous
input, combined with hitting "break" while it is printing error messages
seems to cause the same effect.

repeat 10 (fortune; sleep 10)

Interesting, eh?
