Freeradius is crashing in krb auth

[Lisa Besko]

Freeradius keeps crashing on us.  I finally put it in debug mode and 
this is the tail end of the messages I get before it dies:

--------------------------------
     users: Matched entry DEFAULT at line 5
   modcall[authorize]: module "files" returns ok for request 9
rlm_pap: WARNING! No "known good" password found for the user. 
Authentication may fail because of this.
   modcall[authorize]: module "pap" returns noop for request 9
modcall: leaving group authorize (returns ok) for request 9
   rad_check_password:  Found Auth-Type Kerberos
auth: type "Kerberos"
   Processing the authenticate section of radiusd.conf
modcall: entering group kerberos for request 9
Segmentation fault (core dumped)
-------------------------------

Part of what is frustrating is I've been running this same configuration 
on another system and it's fine.  I just moved it to a production system 
and I'm having issues.  They are both running FreeRadius 1.1.7_3 and MIT 
  Kerberos 1.6.3_5.  The setup that works well is running FreeBSD 7.0 
Stable on an i386 system.  The one that keeps crashing is running 
FreeBSD 7.1 PreRelease on an AMD system.  Anyone have any ideas about 
what is happening here?
