MessagePack stores the length of a string, binary value, array, or object in at most 32 bits. For a larger value, to_msgpack wrote no length at all, so the output could not be read back. It now throws out_of_range.412, which BSON already uses for its 32-bit length fields. The check lives in one function, so each length is written by an if/else chain that ends in a plain else, without a condition that can never be false. It is tested with string and binary types that report a size beyond UINT32_MAX without allocating it, like the BSON tests do. Signed-off-by: Niels Lohmann <mail@nlohmann.me>
