[freeipdb-hackers] ipdb_ck.pl DANGEROUS

[Anthony DeRobertis]

In the first block, right after $first = 0 insert:

        my @PRTNS = ();
        my @FIRST = ();
Without these lines, ipdb_ck.pl clears in-use interior nodes!

[ Note: for some reason, I'm not seeing it loop [ while($changes) ]
  as it should after inserting these lines. Naturally, it works just
  fine when you run ddd on it. Suspect perl bug. ]
