Cache_Lite Bug on Resave?

Hi, I seem to be running into some trouble with Cache_Lite upon resaving data for caching. The below script demonstrates the problem. I am using Cache_lite with read and write checking. ---------------- if ($data = $cache->get('test')) {

    var_dump($data = unserialize($data));
    // Success
    $data->now();
    $cache->save(serialize($data), 'test');
    // Failure

} else {

    $data = new test();
    $cache->save(serialize($data), 'test');
    // Success

} class test {

    var $now = null;
    var $then = null;

    function test()
    {
        $this->then = time();
    }

    function now()
    {
         $this->now = time();
    }

} ----------------- For some reason that is totally escaping me, when doing the read control, it fails: line 341:

$hashControl = "                      -155960464"

//Correct line 344: $data = @fread($fp, $length); // Incorrect, it only reads in a incomplete amount of the data $data = "O:4:"test":2:{s:3:"now";i:1045743845;s:4:"then";i:1"; // It should be $data_in_reality = "O:4:"test":2:{s:3:"now";i:1045743845;s:4:"then";i:1045743833;}"; // And hashData is incorrectly evaluated to

$hashData = "                     -1334859930"

What puzzles me is that when doing the initial $cache->save(), it works absolutely fine. Why is it that my recaching fails? Thanks, Michael
