port numbers should always be interpreted as decimal 

per POSIX and RFC 3493:

If the specified address family is AF_INET, AF_INET6, or AF_UNSPEC,
the service can be specified as a string specifying a decimal port
number.

021 is a valid decimal number, therefore, interpreting it as octal
seems to be non-conformant.
