thanks a lot, sorry for the noise.

Hi,

I found that the memory leak is actually related to APC,
even with the latest version of PHP (5.3.25) and latest version of APC
(3.1.13),
the memory leak is still there, to re-produce the bug,
just run this script and watch the memory usage of the php process
(please run with: php -d apc.enable_cli=1 )

<?php

touch('file1.php');
while (true) {
$file = 'file1.php';
require($file);
}

if run with -dapc.enable_cli=0, it does not leak memory.

thanks.

even with the latest version of PHP (5.3.25) and latest version of APC
(3.1.13),

Please submit the bug on bugs.php.net with package "apc" - putting there
reproducing script and describing exactly what you see when it is running.

Just to make sure it's extra clear, APC 3.1.13 is a beta release. 3.1.14
was released and un-released because of memory leak issues.

If you're still using PHP 5.3 you might want to see if the issue is still
there in the latest stable APC

Hi,

Thanks for your information.
I also tested the latest stable version of APC
(3.1.9http://pecl.php.net/package/APC/3.1.9),
which has the same problem.

More information about this bug:

To stably re-produce the bug, we need create 2 files.
// file1.php, can be empty

// leak.php
<?php

while (true) {
$file = 'file1.php';
require($file);
}

then run: php -d apc.enable_cli=1 leak.php

hope this helps, thanks.
