Ok, after puttering with this for a while, I thought I'd see if anyone has any
insight on this wierdness.  It's damned odd, since this works just fine on the
same box using snort 1.7 and an older version of snort_stat.

With Snort Version 1.8.2-beta0 (Build 85) and
# $Id: snort_stat.pl,v 2001/08/24 01:24:43 yenming Exp $

I grabbed 4 entries from my full alert file and placed them into a small file
called testme.  Then 'cat testme | ./new_snort_stat.pl'.  Now, I would expect
the normal output, but instead I get almost nothing:

All of the stats show _nothing_.  No alerts or anything.  But--In the testme
file, I have the following:
