4-byte ASN numbers being expressed as floating point numbers by ralabel

[The Branches]

Carter,

I downloaded and built argus-3.0.8.rc.5 and argus-clients-3.0.8.rc.1 
(--with-GeoIP=yes) on an Ubuntu 12.04 box today.  Thanks to your helpful 
documentation, I was able for the first time to get ralabel to mark 
records with source and dest asn.  It is overall doing a beautiful job, 
but I noticed in my results a few records with funky asn numbers being 
reported by ralabel, in floating point decimal format for some reason.  
It appears to be happening only with 6-digit ASNs (or more likely 4-byte 
ASNs).

Here is my  /etc/ralabel.conf:
RALABEL_GEOIP_ASN=yes
RALABEL_GEOIP_ASN_FILE="/usr/local/share/GeoIP/GeoIPASNum.dat"

Here I have a single-record argus data file containing an IP in such an ASN

root at nids:~# ra -r test.arg
          StartTime      Flgs  Proto            SrcAddr  Sport   
Dir            DstAddr  Dport  TotPkts   TotBytes State
  06/25/14.00:00:00  e           tcp      110.77.193.19.62694     ->     
183.95.147.129.https        35      26462   FIN

And here I run ralabel against it

root at nids:~# ralabel -f /etc/ralabel.conf -r test.arg -s sas:10 sco saddr
        sAS sCo            SrcAddr
                                 0
       2.18  TH      110.77.193.19

No idea what the line with the lonely "0" is about, but 2.18 sure looks 
like a funny ASN.   Do I need to provide some special format string to 
get this to output right or have I flushed out a bug?

I love being able to aggregate on ASN now.    Thanks for this wonderful 
program.  It's been one of my favorite tools in my networking toolbox 
for years and it just keeps getting better...
