commBind: Cannot bind socket FD ... on squid-2.2.STABLE3

Hello all!

  I recently compiled and installed squid-2.2.STABLE3. All seems to work
fine but I noticed that my cache.log is full of messages of the
following type:

        commBind: Cannot bind socket FD ХХ to ХХХ.ХХХ.ХХХ.ХХХ:0: (22) Invalid
argument

where ХХХ.ХХХ.ХХХ.ХХХ is the IP address specified in
tcp_outgoing_address (this is the address of the machine Squid runs on).

  I found in Squid-2.2 bugs list
(http://squid.nlanr.net/Squid/v2/2.2/bugs.html) that this problem was
solved in STABLE2. Yes, Squid does not die but I'm still getting those
annoying messages.
  So what's happening? Any idea?

Compilation options for squid:
--enable-dlmalloc
--enable-cachemgr-hostname=proxy
--enable-err-language=Russian-1251
--enable-snmp
--enable-xmalloc-statistics

Operating system: SCO UnixWare 2.1.3

With best regards,
