Description:
------------
I have column type TEXT.
When I read it over odbc_result, it works fine.
When I read it over PDO, column is empty.
More, all next readed columns after this column are empty too.
For example: SELECT ID, CSN, Spec FROM MYTABLE
When CSN column type is TEXT, I obtain empty data for CSN a Spec columns.
I have downloaded http://snaps.php.net/win32/php5.2-win32-latest.zip
before I send this bug.

Reproduce code:
---------------
if($sth = $pdo->query( "SELECT ID, CSN, Spec FROM MYTABLE" ))
{
	while( ($row = $sth->fetch(PDO::FETCH_NUM)) )
	{
		echo "ID:".$row[0]."<BR>";
		echo "CSN:".$row[1]."<BR>";
		echo "Spec:".$row[2]."<BR>";
	}
}


Expected result:
----------------
Not empty $row[1] and $row[2]

Actual result:
--------------
Empty $row[1] and $row[2]
