I can't reproduce this behaviour.

So, how should I avoid them? pdisk renumbers partitions in this situation

They are place-holders. If you create a new partition, it will use that
number. It is simply there to preserve the partition numbers after it
(which should be under 15, anyway)

Why? I don't understand what your saying - Apple_Void isn't a partition.
It's an empty partition map entry. For example, with DOS disk labels,
you can have partition 1 and 3, but no partition 2 and 4.
I can change this behaviour, but I think preserving numbers is good for
/etc/fstab
