I am the author. I have no problem with that part of the book: The quote 
is correct.

Both C and C++ explicitly state what I wrote above. That guarantee is 
necessary so that looping over the elements of an array does not make 
the program illegal just because the array may be sitting at the end of 
an allocated page.

D does not reject that part of C's memory model.
