in a difficult situation where I need it to work as before. I won't go into
all the details but I have an existing app that not only uses freetds as its
intended but also parses it and uses it within an application. I can't alter
the app and need the functionality we have been using up to now.

Maybe a little of both.  I would say it's undesirable.  

What's happening: tds_read_config_info() calls parse_server_name_for_port()
whose real purpose is to interpret instance\hostname and hostname:port
strings.
It's not supposed to interpret the [servername] string in freetds.conf, 
but that's what it's doing.  

If you set TDSDUMPCONFIG, you'll see near the top of the log it's looking
for
your 'server\name' name, and then another message, "Parsed servername, now
back on 0" that means it parsed for a port number and came up with zero.  

I think the idea, once upon a time, was that 

        tsql -S 'instance\servername'
or
        tsql -S 'servername:port'

would be a way to override the instance/port in freetds.conf.  But I'm not
so
sure that's such a great feature and, even if it is, it belongs properly to 
the tsql application, not libtds.  

I would try deleting the call to parse_server_name_for_port() and see if 
that solves your problem. 

HTH.
