How do I debug a Segmentation fault from ntpmon?

I don't think there is any ctype involved on our part.  We are calling 
socket.inet_ntop() from python.

The Segmentation fault printout always appears near the bottom of the the 
mru printout.  At least in the normal case, all the hosts involved have 
names so inet_ntop() wouldn't get called.

I suspect you are getting garbage from ntpd.

Actually, if I understand things...  There is no need to call inet_ntop(). 
 You get a text form of an IP address and turn it into a binary form so 
you can do a name lookup.  If the name lookup fails, you convert the 
binary form back to text.  My guess is that you are getting garbage so the 
convert to binary step is failing.
