(1) do not cast it to (void *), and
(2) print it as 0x%x, rather than %p.
This is not perfect (because the data being printed is "int32_t"-sized), but
is more correct than printing it as a pointer because the data is _not_ a
pointer, it is data to be printed in hex, and on some systems, pointers are
wider than the data items being printed, which leads to excess and misleading
output. The only 'right' solution to this is to have a printf specifier
that prints the fixed-sized types the right way, and that's not really
practical.
error checking in the DIAGNOSTIC case. These changes might be backed out,
if it's decided that MINBUCKET should be 5 (rather than 4) on the alpha.
However, doing that has its own set of nasty consequences.
