I don't know exactly *how* it might trigger that crash, but it seems a data corruption, and that code is doing exactly that. In addition, below, the segment selector is totally fucked up. It is a ring 0 GDT segment, which is however non existant. It would exist only if there were a third CPU, and would be a NULL descriptor anyway.
