dccifd 1.2.49 seg fault

I'm trying to use dccifd with Spamassassin 2.63 connecting to our local dcc 
server, and at Spamassassin startup we get this message:

DCCifd -> check skipped: Illegal seek Died 
at /usr/lib/perl5/site_perl/5.8.0/Mail/SpamAssassin/Dns.pm line 632.

dccifd dumps core at that point and running gdb on the core file shows:

(gdb) where
#0  0x0804ed3b in rcpt_st_alloc ()
#1  0x0804c923 in do_rcpts ()
#2  0x0804d64d in job_start ()
#3  0xb77b5dac in start_thread () from /lib/tls/libpthread.so.0
#4  0xb7754a8a in clone () from /lib/tls/libc.so.6

We are running RedHat AS 3.0 update 1 with glibc 2.3.2-95.6.

Any thoughts on what might be causing this?
