A GC dont' try to recognize a valid/invalid reference, it is invoked to free 
unused memory, which it assume point to valid memory.

Anyway I still don't understand the goal of this discussion.
Do you want to add some managed object in fpc? OK, but I suggest to start 
studing how GC works in Java, Python and dotnet.

As for me I'd rather ask for not managed Interfaces in Delphi (fpc ones are 
ok).



Bye Uberto
