From: t...@php.net
Operating system: FreeBSD, MacOSX
PHP version: 5.2.9
PHP Bug Type: Output Control
Bug description: headers_sent() reports 'true' after system() call in
ob_start()
Description:
------------
This is the php -v from one of the servers:
PHP 5.2.9 with Suhosin-Patch 0.9.7 (cli) (built: Apr 9 2009
03:31:34)
Copyright (c) 1997-2009 The PHP Group
Zend Engine v2.2.0, Copyright (c) 1998-2009 Zend Technologies
This is another one (macosx):
PHP 5.2.9 (cli) (built: Apr 2 2009 16:07:08)
Copyright (c) 1997-2009 The PHP Group
Zend Engine v2.2.0, Copyright (c) 1998-2009 Zend Technologies
with Xdebug v2.0.4, Copyright (c) 2002-2008, by Derick Rethans
Right after my system() call, headers were send. This works
differently in 5.2.6 and 5.2.8. I've scanned through
UPDATING/CHANGELOG but couldn't find anything.
I've disabled APC to make sure it's not connected.
php -m:
[PHP Modules]

Also reproduced with RC1 on 5.3:
PHP 5.3.0RC1 (cli) (built: Apr 9 2009 15:45:09)
Copyright (c) 1997-2009 The PHP Group
Zend Engine v2.3.0, Copyright (c) 1998-2009 Zend Technologies
Reproduce code:
---------------
<?php
ob_start();
system('file -i -b /path/file.txt');
$contents = ob_get_contents();
ob_end_clean();
var_dump(headers_sent($file, $line), $file, $line);
Expected result:
----------------
headers_sent() should return false.
Actual result:
--------------
headers_sent() returns true, with empty $file and $line = 0.
