In C++, throwing an exception while unwinding is a fatal error.
Well, you still can throw it, but you're not allowed to let it
escape the destructor (you need to catch them before they would
chain).
C++ also provides a way to inspect if you're in the middle of the
stack unwinding caused by an exception, to make this a bit more
controllable, and I would think we should provide the similar
primitive:
