I have just found a bug in CoreWarsDeluxe for the PC.  It involves
the MOV ADD and SUB commands when using predecrement in the B-field.
Here's how I found it:

	mov 2,<2
	jmp -1
	dat #1

What happens is when CWD reads the A field, it goes ahead and grabs
a copy of what it is going to move.  Then if the B field decrements
that same instruction, the mov works as normal except that it uses
the copy of the instruction that has not been decremented.

The same goes for the ADD and SUB commands.

Has anyone ran the test programs on CorewarsDeluxe or on KoTHPC?
