Luiz Americo,
Anyway, calling manually _Release avoid the leak and i will stay with it for now (I hope did not break anything).

It can work for that case, but I think that is not a good ideia.

If you are using a TInterfacedObject descendant, it will call the _Release when out of context, so in that especific case seems to never go out of context, and then you _realease call works, but in other place it can go out of context before, and the you will have others AV.

- As Joao suggest, the best way is create a weak reference, where when 2 objects need to reference each other one should use Pointer to hold one reference
- Avoid circular reference
- Create a Finalization method that will set one of the references to "nil"
