Description:
------------
Run the test script. In it I am declaring an anonymous function (because I want to be able to unset it later) using eval (my actual function is much more complicated, and I really need to use eval) and unseting it. If you check memory usage while executing this script you will see it will rise, rise and crash.

What is weird, is that if I execute the same test script but without using eval (code below) it works just fine, no memory leak, no crash... nothing. Apache barely uses any memory.

<?php

set_time_limit(0); 
ini_set('memory_limit','-1');

$aaa = array();

for ($i=0;$i<10000000;$i++) {
	
	$aaa[$i] = function($iduc,$cp_ccp) {
	
		return ($cp_ccp and $iduc);

	};

	unset($aaa[$i]);
	
}

?>

Test script:
---------------
<?php

set_time_limit(0); 
ini_set('memory_limit','-1');

$a = array();

for ($i=0;$i<100000000;$i++) {
	
	eval('
	
		$a[' . $i . '] =
		function($i,$da_ca,$iduc,$cp_ccp) {
		
			return ($cp_ccp[' . $i . '] and $iduc[' . ($i+1) . ']);
	
		};
	
	');

	unset($funcao_testar_retorno_parametros[$i]);
	
}

?>

Expected result:
----------------
Variable should be unsetted and memory released.

Actual result:
--------------
Variable does not get out of memory and in a couple minutes crash Apache with lots of error messages complaining about lack of system memory on error_log.
