Before Change

    Load YAML mappings into an ordered dict to preserve key order.
    loader.flatten_mapping(node)
    nodes = loader.construct_pairs(node)
    dups = [k for k, v in Counter(k for k, _ in nodes).items() if v > 1]
    if dups:
        raise yaml.YAMLError("ERROR: duplicate keys: {}".format(dups))
    return OrderedDict(nodes)

After Change

    loader.flatten_mapping(node)
    nodes = loader.construct_pairs(node)

    seen = {}
    for (key, _), (node, _) in zip(nodes, node.value):
        line = getattr(node, "__line__", "unknown")
        if key in seen:
            fname = getattr(loader.stream, "name", "")
            raise yaml.YAMLError("ERROR: duplicate key: \"{}\""
                                 " in {} line {} and {}"
                                 .format(key, fname, seen[key], line))
        seen[key] = line
