no, because the duplicate is done before the method returned, either by you
if you implemented that method (i.e. it's a local call) or by the ORB if
it returns from an up-call (i.e. the method is part of an auto-generated proxy). 
All is fine.

However, if the pointer is from an 'in' parameter of a method, you do need
to duplicate yourself.

void ServerImpl::registerObject(const char *name, Object_ptr object)
{
  table[name] = Object::_duplicate(object);
}
