Thanks for that. I'll check as soon as I get my vserver chroots going. I'll put a clean F12 from the backup I took in there and see what it does. Hopefully it's just a libgcc mismatch issue - which would be worrying, but it'd only arise in a franken-distro half way between F12 and F13 (which is, sadly, all I have handy at the moment).
