DEC 5000/200 running Ultrix 4.2
Sun Sparcstation-2 running SunOS 4.1.2

tcsh 6.02 compiled with /bin/cc under Ultrix and gcc-2.2.1 under SunOS.

I get the following weirdness.  Is this normal behaviour?  I got the same
weirdness in /bin/csh under Ultrix and SunOS.

gingko% echo $version
tcsh 6.02.00 (Cornell) 92/05/15 options 8b,nls,dl,al,dir
gingko% echo | echo
gingko% Reset tty pgrp from 28435 to 26785
gingko% jobs
[1]  + 28435 Running                echo |
gingko% fg
echo |
gingko% jobs
gingko%

Unfortunately, yes.  This is an example of one of a few wierd bugs that
exist under the c-shell.

Seems to me like the problem lies in the fact that you are using the
built in echo and not /bin/echo that causes the bug to surface:

(54:ashone:~) echo $version
tcsh 6.01.00 (Cornell) 12/19/91 options 8b,nls,dl,vi,al,dir
(55:ashone:~) echo | echo
(56:ashone:~) Reset tty pgrp from 1645 to 639
(56:ashone:~) jobs
[1]    Running                echo |
(57:ashone:~) %1
echo |
(58:ashone:~) 
(58:ashone:~) jobs
(59:ashone:~) /bin/echo | /bin/echo

(60:ashone:~) jobs
(61:ashone:~)
