http://bugs.debian.org/263154

iptables 1.2.11 segfaults when given a domain name that resolves 
to multiple ip addresses. The situation is the same for kernel 
versions 2.4.26 and 2.6.7.

As an example:

  # iptables -I INPUT -s google.com -j DROP
  free(): invalid pointer 0x8055a4c!
  Segmentation fault
