Thank you for responding Julian.

I ended up creating a PR and a thread on forums.freebsd.org..

I booted off of the 9.2 CD into LiveCD and had the same issue, fsck_ufs
segfaulting.

After many many hours of troubleshooting (documented in the forum thread),
I ended up using the binary from a 9.0-RELEASE box, which worked fine.

Thank you
