Although I'm not as worried about that prospect as you are, I would also 
appreciate a fix for the problem, so long as it doesn't hurt performance in the 
common case where the fix isn't needed. As I understand it, you want the the 
conservative object scanner to count any pointer to somewhere in (or just past 
the end of) an object, as opposed to counting only pointers to the start of the 
object. That would be a reasonable thing to add, perhaps conditionally compiled 
so that it doesn't hurt performance on typical architectures today.
