It's as close as you can get to useless knowledge. It's like asking a pilot "exactly how will the aircraft break apart if you nose dive it at high speed into the ground?"
This analogy makes a lot of sense until you need to deal with an exception emanating from a destructor... then it looks a lot more like "what's the proper way to hold a chainsaw"
I want to play a game. In your hands is a chainsaw about to be destructed. Another exception is already in flight. Live, or std::terminate. Make your choice. -Jigsaw
