cryptsetup-luks segfault

[Gentist]

I'm following this guide: http://gentoo-wiki.com/SECURITY_System_Encryption_DM-Crypt_with_LUKS

However, upon bootup, when decrypting root using the script provided in the link, cryptsetup segfaults (after successfully decrypting root), causing the script to think that it failed, which throws me back at a shell. I'm using the static binary cryptsetup (luks) for AMD64 (http://luks.endorphin.org/precompiled/cryptsetup-1.0.3-x86_64-pc-linux-gnu-static.bz2).

Does anyone have this problem, or know how to fix it? I suppose a workaround would be to remove any checks from the script, but I don't really have the time for that right now, seeing as I would probably have to rewrite almost the entire script.

Edit: it appears that using the x86 binary works, though I ran in to some other problems.
