(It's 256GB, not 32: the comment was wrong.)
That call only _reserves_ the address space, it doesn't actually
allocate anything. So the amount of memory actually available on your
system is not important at that spot. What _is_ important is that in
the 32-bit executable we are trying to reserve a significant portion
of the 2GB address space of 32-bit programs, while in the 64-bit
executable we reserve a very small portion of the address space.
