malloc_g's CheckedPtr template: Where is it?

Hi all:

According to the Heap Analysis section of the 6.2 documentation,
malloc_g is supposed to have a CheckedPtr template to assist in bounds
checking a pointer dereference. Does anyone know if this was ever
included. I have grepped through my files and do not see that it has
been included. Anyone know of something similar before I go about
writing my own?
