Nothing frees that scalar when the object is rejected for a missing ':' after the key or, from 4.09, for a duplicate key. Duplicate keys are an error unless allow_dupkeys, dupkeys_as_arrayref or relaxed is set.\n\nA process that keeps running after a failed decode retains one key per rejected document, with its size chosen by the sender.
