I had a similar problem (regarding iptables). It seems they are implementing
a new unified interface (NFNETLINK) which might break the userspace
netfilter tools (aka. iptables/ip6tables), unless you use the CVS version of
them. This is was introduced somewhere between 2.6.15 and 2.6.16.
IIRC after disabling CONFIG_NETFILTER_NETLINK (or at least set it to compile
it as a module) and enabling CONFIG_NETFILTER_XTABLES I didn't have any
problems anymore.


Regarding the segfault, I can't help you there ... although I have seen many
applications not longer working on my Debian/testing system lately
(segfault, 'unresolvable relocation error 0x42' most of the time).
The affected applications/debian packages are:
- aide
- samba (libsmbclient, samba, samba-common, smbclient, smbfs etc.)
- autofs

Recompiling those applications via 'apt-get build-dep <package>' and
'apt-get -b source <package>' with gcc-3.4 produces working executables. At
least for samba I also tried recompiling with gcc-4.0, with also worked. It
seems that there is something wrong with the setup Debian's buildd uses ...
... I think I should rather report this bug to the debian-hppa m-l ...
