No, if alignment_power is zero, then pad will not be used because all
the pad lengths will be zero.  In fact, I think we are allocating one
more byte than necessary since the pad lengths ought to be 0 to
(1 << alignment_power) - 1.  I'll pre-approve a patch that changes
  char *pad = NULL;
to
  char *pad = "";
just to silence the warning.
