Processing of a checkgroups control message core-dumps, producing the

The checkgroups report has been sent to $NEWSMASTER and is complete. However,
the work files are still in /tmp. That means for me that the crash happens
when checkgroups tries to execute the final 'rm -f /tmp/$$*' in the
$NEWSBIN/ctl/checkgroups script.

C News runs on a Sun 3/160 with SunOS 4.0.3 here. We guess that the problem
started to occur after the upgrade to C News Patch Level 25-May-1990.

Any idea what happens here? Could an earlier command in the script have
destroyed the environment?

Maybe someone else experienced the same problem. Hmm..?

Thanks in advance for any kind of help.
