With C++ RAII, the dtor gets called when the object goes out of scope. The mechanisms for multithreading always involve passing a callback to be run on a new thread. Thus, I don't think it's possible for an object to be constructed in one thread and destructed in another, since those would have to be different scopes.
Am I right about this? Or are there some cases where an objects ctor and dtor can be called in different threads?
