Summary: bug fix enclosed

Well, since no-one else came up with the answer, I delved into
the uucp source and fixed the bug which was causing core dumps.
A memory fault was resulting from a call to prefix() with a
second argument which was garbage. In anlwrk.c, the function
iswrk(), the code

	static char **listp, *list[LLEN];
	...
	if (listp == NULL || *listp == NULL || listp > (list + LLEN)
	  || !prefix(pre, *listp)) {

obviously was checking one too far. Just change the > to >= so
the test line reads:

	if (listp == NULL || *listp == NULL || listp >= (list + LLEN)

Presto, problem solved. If you have source, you should fix it.
If you don't, get your P-E office to fix it. Since LLEN is 20,
the problem appears if you have >40 files to process for the same
site at one time.

(We had a backlog of 862 files in /usr/spool/uucp, which was what
encouraged me to track down the bug!)
