Throwing an exception copy-initializes a temporary object, called the exception object. The temporary is an lvalue and is used to initialize the variable declared in the matching handler.
If the copy constructor for the exception object type throws during the copy initialization, std::terminate() is called, which can result in possibly unexpected implementation-defined behavior. For more information on implicitly calling std::terminate(), see ERR50-CPP. Do not abruptly terminate the program.
