I can't seem to reproduce this. In fact, I can't seem to build the version
of rakudo specified (git checkout bf29be), because it makes use of a
symbol "PObj_active_destroy_SET", which isn't in parrot r44371 or later.
I have also unsuccessfully tried to reproduce against the latest rakudo
(b348b3ed0464c504b80b159075e5a3773f3ef464) and parrot (r44657).

Since I cannot reproduce this, your best chance is to try to track this
down yourself. If I understand bacek correctly, the suspicion is currently
on the init vtable being called properly (or at all?) when creating some
pmcs.
