okay. this means we should definitely break after a BTX error and *not*
somehow return to business (I've seen a iret somewhere). maybe *then*
we can track the issue.
somehow it seem that *either* esp/ss gets shifted to an area that is
full of 0xff *or* something overflows and kills the whole stack. Or am
I on the wrong track?
cheers
