I've come accross with this problem while trying to figure out NHibernate's Identiy sequence mapping. When the Culture is set as Turkish(tr-TR) a query that includes RETURNING INTO statements throws ORA-03146: Invalid buffer length for TTC field error. Same query executes fine when the culture is set as Invariant or en-US. Here is the template for reproducing(I don't know how to refer to a sample project with an Oracle database, if such thing exist I can update the issue with sample project).

            using (OracleConnection oc = new OracleConnection())
            {
                var culture = CultureInfo.GetCultureInfo("tr-TR");
                Thread.CurrentThread.CurrentCulture = culture;
                Thread.CurrentThread.CurrentUICulture = culture;
                oc.ConnectionString = "User ID=<user_id>; Password=<password>; Data Source=<data_source>;";
                oc.Open();
                string sql = "INSERT INTO ALL_SETS_OBJS (SETOBJID, OID, SETID, CLID, PK1, PK2, PK3, PK4) VALUES " +
                    "(ALL_SETS_OBJS_SEQ.nextval, 28601, 818453, 310, '596', '', '', '') returning SETOBJID into :nhIdOutParam";
                OracleCommand cmd = new OracleCommand(sql, oc)
                {
                    CommandType = CommandType.Text
                };
                OracleParameter nhIdOutParam = new OracleParameter
                {
                    OracleDbType = OracleDbType.Decimal
                };
                cmd.Parameters.Add(nhIdOutParam);
                OracleDataReader dr = cmd.ExecuteReader();
                dr.Read();
            }
            Console.ReadLine();
OracleDataReader dr = cmd.ExecuteReader();
                dr.Read();
            }
            Console.ReadLine();
            Console.ReadLine();
