[PATCH] segmentation fault in free

[Thomas Woerner]

Hello,


I have found a bad bug in iptables. saddrs and daddrs are allocated with calloc in 
host_to_addr if a hostname resolves to more than one ip address, but each array 
element if getting freed in do_command. The first free will free the whole array and 
the others are returning that this is not a pointer or are segfaulting.

Fix for this is attached.


Thanks,
Thomas
