You must not delete the object while it is still in use by the ORB/POA.

One correct way is to:

1. Ask the object's POA to deactivate the object with
deactivate_object().
2. Remove your implicit reference to the object with remove_ref().

You can do 2. at any time after activation. If you do not need an own
reference, you should do that immediately after activation, then
deactivate_object() will cause the object to be deleted when all
references are removed.
