>Description:
when logged into terminal using tcsh 6.12.00 seem's to exit from this command a few times but after repeating it 3 times or so it locks up and wont respon to ctrl C ctrl Z ...cant close it from terminal it happened on
>How-To-Repeat:
in the csh shell ..im not running any other programs in backround..type    
\ \ \ \  & \  & \  & \ % & % \    ..could modify it i guess but thats what i just typed and it does it so..go's through and just exits command not found..No such job (bad job) ..for a few times then after 3-4 times or doing it repeatdly it stops responding no way i know of closeing it,seems to become a zombie process or such?
>Fix:
only way i know of getting your terminal back is to log into another tty and kill - HUP (process id) i press ctrl T ,and kill -HUP that process number then it exits? should be easy to reproduce?
