From NetBSD:

- Keep track of allhost multicast address record we joined into
  each in_ifaddr and delete it when an address is purged.
- Don't simply try to delete a multicast address record listed in the
  ia_multiaddrs.  It results a dangling pointer.  Let whoever holds a
  reference to it to delete it.
