Of course I didn't call free; I was hoping that the reference counter
would solve that little problem. If I need to free stuff myself, I don't
really need a reference counter. In any case, thanks for the answer. I
will give it a try and see what it gives

I'm not sure that is correct. Once you free Test, Pest still points to
the same non existing object and you can use assigned to check it,
