Description:
------------
When testing pdo_odbc on php 5.1.4 with DB2, I got the following test errors when running the standard PDO tests:

PDO Common: PDOStatement iterator [pdo_013.phpt]
PDO Common: PDOStatement SPL iterator [pdo_014.phpt]
PDO Common: PDO::FETCH_INTO [pdo_025.phpt]
PDO Common: extending PDO (2) [pdo_026.phpt]
PDO Common: PDO::FETCH_LAZY [pdo_027.phpt]
PDO Common: extending PDO (3) [pdo_029.phpt]
PDO Common: extending PDO (4) [pdo_030.phpt]

The following error is from pdo_025:

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

$db = new PDO("odbc:db2", "db2user", "db2password");

$db->exec('CREATE TABLE test(id INT NOT NULL PRIMARY KEY, val VARCHAR(10), val2 VARCHAR(16))');

$data = array(
  array('10', 'Abc', 'zxy'),
  array('20', 'Def', 'wvu'),
  array('30', 'Ghi', 'tsr'),
  array('40', 'Jkl', 'qpo'),
  array('50', 'Mno', 'nml'),
  array('60', 'Pqr', 'kji'),
);

$stmt = $db->prepare("INSERT INTO test VALUES(?, ?, ?)");
foreach ($data as $row) {
  $stmt->execute($row);
}

class Test {
  public $id, $val, $val2;
}

$stmt = $db->prepare('SELECT * FROM test');
$stmt->setFetchMode(PDO::FETCH_INTO, new Test);
$stmt->execute();

foreach($stmt as $obj) {
  var_dump($obj);
}

echo "===FAIL===\n";

class Fail {
  protected $id;
  public $val, $val2;
}

$stmt->setFetchMode(PDO::FETCH_INTO, new Fail);
$stmt->execute();

foreach($stmt as $obj) {
  var_dump($obj);
}

?>
