iptables works fine but returns "invalid pointer" when the rule contains host
name which resolves to multiple addresses.
Steps to Reproduce:
$ host rbc.ru
rbc.ru has address 194.186.36.175
rbc.ru has address 194.186.36.178
rbc.ru has address 62.118.249.66
rbc.ru has address 62.118.249.80
rbc.ru has address 194.186.36.150
$ sudo iptables -A FORWARD -s 192.168.0.55 -d rbc.ru -j ACCEPT
Actual Results:  
free(): invalid pointer 0x804c0a4!
$ sudo service iptables status | grep 55
ACCEPT     all  --  192.168.0.55         62.118.249.80
ACCEPT     all  --  192.168.0.55         194.186.36.150
ACCEPT     all  --  192.168.0.55         194.186.36.175
ACCEPT     all  --  192.168.0.55         194.186.36.178
ACCEPT     all  --  192.168.0.55         62.118.249.66

Expected Results:  
$ sudo service iptables status | grep 55
ACCEPT     all  --  192.168.0.55         62.118.249.80
ACCEPT     all  --  192.168.0.55         194.186.36.150
ACCEPT     all  --  192.168.0.55         194.186.36.175
ACCEPT     all  --  192.168.0.55         194.186.36.178
ACCEPT     all  --  192.168.0.55         62.118.249.66
