No. I often need the actual unhashed address in the hex dump so that I
can see if some other pointer is correct.
For example, I could be doing pointer math to calculate the address of
some data inside a block. In this case, I would %px the pointer, and
then hex_dump the block. I can then see not only where inside the block
the pointer is pointing to, but what data it points to.
