Version: news 2.11 patch 7 (and earlier?)

lockf's calling sequence is
lockf(fildes, function, size)
long size;

In expire.c, ifuncs.c and inews.c, lockf is called with a 3rd
argument of 0, not (long) 0 or 0L.  On a 16-bit machine such as XENIX 286,
this is open to failure since a word of garbage will be on the stack.
The fix is obvious.
