Can you tell me how the invisible high-word (invisible in VM-86, and in real mode) could possibly harm something running in VM-86 or read-mode ??? I don't even think it's a BUG. If the transition into and out of VM-86 doesn't handle the fact that the high-word of the stack hasn't been used in VM-86, then that piece of code is bad (the SP isn't even the same stack, BTW).
