Well, that's what I did. I neglected to check if rb_stts were actually used.

I know, that's what Jason described.
I think I now understand why. Prior to
738910c064ff461051cd37e17199f270ff88a9a3, you introduced
c2a0aa3cb733452e749727680e380dca6cc10a68 without actually allocating the
rb_stts pointer, which was really wrong too.
