Description:
------------
Hi,
either the Bug (#42420) is still alive or it is re-alive. But I am not
allowed to re-open it. So sorry for opening a dup.
php -v says:
------------------
PHP 5.2.17-pl0-gentoo (cli) (built: Feb 18 2011 10:01:58)
Copyright (c) 1997-2010 The PHP Group
Zend Engine v2.2.0, Copyright (c) 1998-2010 Zend Technologies
with Xdebug v2.1.0, Copyright (c) 2002-2010, by Derick Rethans
------------------
The PHP died with SegFault on two different machines with two different
Proxies.
regards
Daniel
Test script:
---------------
<?php
$uri =
'ftp://pkg-shadow.alioth.debian.org/pub/pkg-shadow/shadow-4.1.4.3.tar.bz2';
$proxy = 'tcp://proxy:8080';
$opts = array(
'ftp' => array(
'proxy' => $proxy
)
);
$context = stream_context_create($opts);
stream_context_set_params($context, array());
$fh = fopen($uri, 'r', false, $context);
while (!feof($fh)) {
echo "foo\n";
fread($fh, 4 * 1024);
}
fclose($fh);
?>
Expected result:
----------------
many foos ;-) and no segmentation fault
Actual result:
--------------
many foos and segementation fault
------------------------------------------------------------------------
