Diego, I've tracked down the runtime error on x64 with GCC 4.2.3, and have fixed it in SVN trunk. It turned out some inline assembly register constraints weren't strict enough, and this caused problems with the apparently more aggressive optimizer in the latest GCC. Let me know if the fix works for you.
