If you use the iterator adapter and a serializing cache like the following you will crash php:

<?php


set_include_path('/tmp/zf/trunk/library/');
require_once 'Zend/Loader/Autoloader.php';
$autoloader = Zend_Loader_Autoloader::getInstance();
$view = new Zend_View();

try {
    $frontendOptions    = array(
        'caching' => true,
        'lifetime' => 72000,
        'automatic_serialization' => true
    );
    $backendOptions = array(
        'cache_dir' => '/tmp/invite_vcfront' // Directory where to put the cache files
    );
    $cache = Zend_Cache::factory('Core','File', $frontendOptions,$backendOptions);
    Zend_Paginator::setCache($cache);

    $it = new ArrayIterator(array('test' => 'test', 'test2' => 'test2'));
    $paginator = Zend_Paginator::factory($it);
    $paginator->setItemCountPerPage(10);
    $paginator->setCurrentPageNumber(1);
    $paginator->setView($view);
    // var_dump($paginator->getIterator());
    foreach($paginator as $page){
        echo var_dump($page)."\n";
    }

} catch (Exception $e) {
    echo $e;
}

echo "END\n";

First run (not cached)

php test.php
string(4) "test"

string(5) "test2"

END

Second run (cached)

php test.php
Segmentation fault

After cleaning cache this restarts on first run

The problem is that Zend_Paginator caches an instance of LimitIterator where is a bug in php:

To solve this I created a new class Zend_Paginator_SerializableLimitIterator.
