Leafnode segfaulting in texpire & fetch
Texpire started segfaulting on me a couple days ago, right
at the very beginning of the program. Today, fetch also started
segfaulting. It's working now, but I just wanted to let people know in
case it happens to anyone else.
Purging and reinstalling leafnode (1.4-10) did not help, but deleting
/var/spool/news (230MB) and reinstalling fixed it. I suspect one of the
configuration files got corrupted, but I'm not sure. (I'll have to
re-download all the news, but a lot of it was supposed to have expired
anyway.)
The strace from both programs looks similar:

I wondered if the /var/lib/leafnode/groupinfo file could be the culprit,
but I don't have it anymore. I pulled a copy from yesterday morning's
backup and fed it to leafnode, but no segfault.
