Description:
------------
Hello,

Sorry for my bad engish. After some segmentation faults I compiled PHP with --enable-debug, and then I have these memory leaks.

Reproduce code:
---------------

Expected result:

No memory leaks

Actual result:
--------------

Thank you for this bug report. To properly diagnose the problem, we
need a short but complete example script to be able to reproduce
this bug ourselves. 

A proper reproducing script starts with <?php and ends with ?>,
is max. 10-20 lines long and does not require any external 
resources such as databases, etc.

If possible, make the script source available online and provide
an URL to it here. Try to avoid embedding huge scripts into the report.

[2006-04-07 09:25 UTC] info at talte dot net

Script source:

<?php
// This file will generate and return the main page of the site
$CONF = array();
$CONF['Self'] = 'index.php';

include('./config.php');

selector();

?>

Also I have segfaults with other scripts,

e.g.

Also, if you need these:

require_once('./global.php');
require_once(DIR . '/includes/functions_cron.php');

You can find them in http://www.sportorbita.com/bulletin/global.php.txt and http://www.sportorbita.com/bulletin/includes/functions_cron.php.txt

Thank you.

[2006-04-07 09:39 UTC] tony2001@php.net

Please, try to provide a short but complete reproduce script, without any includes, max 20 lines long.
Thank you.

[2006-04-07 12:52 UTC] info at talte dot net

I don't know where exacly memory leak is, so I can't do 20 lines from these scripts.

[2006-04-07 16:38 UTC] tony2001@php.net

Sorry, I doubt we're going to debug your huge scripts.
