On the 80386 in either 80386 protected mode or 80286 protected mode the
program crashed the system. On the machine running in 80286 mode it was
caught by the kernel debugger, but I was not able to restart and get a ^C
in to stop the program before it crashed again.

Ah, Intel. Tests on a 68000 (yes, a real 68000) running System V.2 will
be done shortly.
