A sample is N1256 6.5.9p6:

   "Two pointers compare equal if and only if both are null pointers, 
both are pointers to the same object (including a pointer to an object 
and a subobject at its beginning) or function, both are pointers to one 
past the last element of the same array object, or one is a pointer to 
one past the end of one array object and the other is a pointer to the 
start of a different array object that happens to immediately follow the 
first array object in the address space.94)"
