Actually, the data segment in separate I/D programs begins at location 2.
This is to confirm to K&R's dictum that ``it is guaranteed that assignment
of the constant 0 to a pointer will produce a null pointer distinguishable
from a pointer to any object''.

A while back there was a drawn-out discussion of de-referencing null
pointers, and I believe this fact was mentioned in passing.  A look at
the source to ld will confirm it.
