Description:
------------
When using current PHP5.3 CVS version a string-limit around 980 bytes occours when reading text-data. The maximum length seems to differ when the table has another structure but is always around 980 bytes. When reading untill a = 981 everthing works fine.

Reproduce code:
---------------
<?php

$oDb = new PDO('sqlite:test.sqlite');

$oDb->query('CREATE TABLE test (a, b)');

$sStr = '';


for($i = 0; $i < 1000; $i++) {

  $sStr.= 'A';

  $oDb->query('INSERT INTO test (a, b) VALUES (\''.$i.'\', \''.$sStr.'\')');

}

class test {

}


$oStmt = $oDb->query('SELECT * FROM test WHERE a = \'982\'');

$oResult = $oStmt->fetchObject('test');

print_r($oResult);


?>

Expected result:
----------------
test Object ( [a] => 982 [b] => AAAAA ... a string containing 982 'A' )

Actual result:
--------------
Fatal error: Call to a member function fetchObject() on a non-object in sqlitetest.php on line 28
