I had that same issue at the weekend. Somehow my amd64/x86 multiarch
machine had got libc6:i386 at 2.18 but libc6:amd64 was at 2.17. I think
it was this mismatch that was throwing segfaults.

In the end, I was able to complete the upgrade by:
 * Download the libc6:amd64 deb
 * dpkg-deb --extract <deb> <tmp folder>
 * dpkg-deb -e <deb> <tmp folder>
 * Edit <tmp folder>/DEBIAN/preinst and insert "exit 0" near the top
 * dpkg-deb -b <tmp folder>
 * dpkg -i <new deb>

This skipped some checks, but it did get things back in sync and I was
able to complete the upgrade.

The joys of running unstable(!)
