Well, it won't be as easy. The trap in non-canonical address
access attempt will point us back to IP which issued this
intruction, so this approach will not work.

Jumping to random address is inacceptable. So I think we should
stick with nil dereference and encode both error and line number
into sp (64 bits is more than enough for that).
