This is in C++

As we discussed this quarter, throwing exceptions from destructors is generally considered to be extremely problematic, so much so that we're advised never to do it. Yet C++ doesn't explicitly forbid it, so it would be possible to write a class whose destructor threw an exception.

Suppose you did write such a class:

class Throwing { public: Throwing() { } ~Throwing() { throw std::runtime_error{"doh!"}; } };

Are there any circumstances in which this throwing destructor would be problematic? If so, demonstrate such a circumstance (e.g., by writing a C++ function that would be problematic) and briefly explain what is problematic about it. If not, demonstrate what a problematic destructor would actually look like (i.e., what else would need to be true about it, if just throwing an exception isn't enough?).
