Summary0000290: Function call leaks memory
Description

Xdebug leaks memory on every function call. A code to reproduce this behaviour is in simplicity following:

<?php

$a = 'foo';

function bar($a)
{
$b = $a;
}

for ($i = 0; $i < 10000000; $i++) {
bar($a);
}

?>

Execute that and watch the memory usage climb for example using "top" command (and noticing disk swapping if you don't do anything).

Xdebug version xdebug-2.0.0RC4
PHP-version 5.2.3

Both PHP and Xdebug are compiled directly from sources and default settings are used in both to make sure that the ones included in Debian don't interfere with testing.

This also happens on a few other machines with Ubuntu Feisty installed (by using the PHP version 5.2.1 that is in it).
