[Vm-dev] I think I've found a bug in the 64-bit Squeak VM memory compactor

[John M McIntosh]

PS the reason why David thundered into this is because  

(a) on a 32bit system with 32bit image the oops start address is never zero, base is constant 0
(b) on a 64bit system with 64bit image the oops start address is never zero, base is zero
(c) on a 64bit system with 32bit image the oops start address is zero, offset by the mmap as the base
(d) on a 32bit system with 64bit image the oops start address is never zero (and the image size would be less than the 32bit address range), base is constant zero
