<![CDATA[1) Preconditions and circumstances
Having a very long connect string the ODBC driver crashes in SQLDriverConnect.
2) Solution to the problem
Install a new ODBC-driver.
3) Probability that the error occurs
For very long connect strings 100%. However, those connect strings would not
lead to a connect to the DB anyway.
4) Workaround
Do not use connect strings with more than 255 characters per keyword/value pair.]]>
