Avi Kivity 1a99c2630c Format nested exceptions in std::exception formatter (#4844) ... Detect when a std::exception also derives from std::nested_exception (e.g. via std::throw_with_nested) and unwind the whole chain, joining each level with ": ". The type-name flag ({:t}) is honored at every level, and the std::exception_ptr formatter inherits this behavior.
