I understand that when something is thrown, the stack is 'unwound' to the point where it is caught, and the destructors of class instances on the stack in each function context are run (which is why you should not throw an exception from a destructor - you could end up throwing a second one)...but I wonder where in memory the object that I have thrown is stored while this happens?
Is it implementation dependent? If so, is there a particular method used by most popular compilers?
