The type of variable pointed to by pivs is unsigned long, but the type used in sizeof is a pointer type. Change it to unsigned long.
Thanks, but there's nothing in this changelog which explains why a -stable backport is being proposed. When fixing a bug, please always describe the user-visible effects of that bug.

Is there any situation in which sizeof(unsigned long *) != sizeof(unsigned long)?
