No close support in PHP 5.3.2-1ubuntu4.2

Question

I just realized that a little PHP does not work correctly on one server, but it works on another.

They both run Ubuntu 10.04 with PHP PHP 5.3.2 (PHP 5.3.2-1ubuntu4.2 with Suhosin-Patch (cli) (built: May 13, 2010 20:03:45))

I am testing using:

$f = function() {};

var_dump($f);
die();

On a server that is running, the result is:

object (close) # 1 (0) {}

In one that does not, the result is:

UNKNOWN: 0

What am I missing?

[edit]

It seems that the problem is related to having 2 closures in one file:

<?php
$f = function() {};
$f2 = function() {};

var_dump($f);
var_dump($f2);
die();

Outputs:

UNKNOWN: 0
object (Closure) # 1 (0) {}

After another Googling combined with the ircmaxell hint on phpinfo, I got a hint of eaccelerator.

, , eaccelerator 0.9.6.1, , , 0.9.6.
