sqsh segfaults at startup (after libc update?)

[knb]

command: sqsh -I /etc/freetds/freetds.conf -Smysrv -Uknb -Pverysecret -Dmydb

Expected: Establish a connection to a MSSQL database server, open a command-line prompt

Instead: cannot connect to database server, no output except: "Segmentation fault (core dumped)"

Wild guess:

This morning I have run the software updater,
a lot of libraries were updated from the standard repos_

command line client from command line clinet "isql" (from unixodbc package) works

command line client sqhs works with

"sqsh -v" -- reports version number

and with

sqsh --invalid-args // reports command line options list

but cannot establish connections
