innd 2.2.1 crashes on message with bad Distribution: line

[Joe Ramey]

Last night my innd 2.2.1 (running on a Sparc server with Solaris 2.6)
dumped core.  I found the cause was an article that came in with a bad
Distribution line:

Distribution: ,

I made a quick fix to keep my innd from crashing if another such
article comes in:

*** innd/art.c.ORIG     Sun Aug  8 16:56:53 1999
--- innd/art.c  Thu Nov 18 14:18:35 1999
***************
*** 2285,2291 ****
      /* If we limit what distributions we get, see if we want this one. */
      p = HDR(_distribution);
      distributions = *p ? CommaSplit(p) : NULL;
!     if (distributions) {
        DISTparse(distributions, &Data);
        if (ME.Distributions
         && !DISTwantany(ME.Distributions, distributions)) {
--- 2285,2291 ----
      /* If we limit what distributions we get, see if we want this one. */
      p = HDR(_distribution);
      distributions = *p ? CommaSplit(p) : NULL;
!     if (distributions && distributions[0] && *distributions[0]) {
        DISTparse(distributions, &Data);
        if (ME.Distributions
         && !DISTwantany(ME.Distributions, distributions)) {


Unfortunately when I tested the patch it worked, so I sent the bad
article to all my downstream feeds, and they crashed. :-(

I think the right fix is probably to reject the article?
