Thanks, I can reproduce the problem... wow, this is really odd. The 32 Bit version works just fine, the 64 Bit one crashes.
EDIT: seems to happen with the other 64 Bit releases (Debian, FreeBSD, NetBSD) as well.
EDIT2: congratulations, you found a yet undiscovered bug caused by accessing a bad memory address. I guess it's time for a Prerelease 2 then...
