Please post a TDSDUMP log that includes the error.  I can't reproduce it with 
bsqlodbc:

$ cat /tmp/sql && bsqlodbc -S $S -U $U -P $P -i /tmp/sql 
if object_id('a') is not NULL 
        drop table a
go
create table a( a int not NULL)
go
select * from a
go
update a set a = 'a'
go

         a
- ---------
bsqlodbc: error -1: SQLExecute: SQL_ERROR: failed
bsqlodbc: error 245: 22018: [FreeTDS][SQL Server]Syntax error converting the 
varchar value 'a' to a column of data type int.
