Except this isn't just a move.

No, the number of destructor calls must be equal to the number of
constructor/postblit calls. Otherwise reference counting types are not going to
work.

Postblit must be called in the given example.

Count: 1 - create
Count: 1 - fun call
Count: 0 - destructor (deallocate memory)
Count: segfault, memory has already been freed - destructor (deallocate memory)

Something is still wrong in the given example.
