Memory leak confirmed for the following configurations:

PHP vc9 5.3.15, thread safe version + Apache Httpd 2.4.2 + Win XP SP3 
PHP vc9 5.4.5,  thread safe version + Apache Httpd 2.4.2 + Win XP SP3 

Running Test script:
--------------------
for($i=0; $i<100;$i++) {
  is_readable("c:\\temp");
}

PHP vc9 5.4.5 tested on WAMP stacks:
------------------------------------

XAMPP USB Lite 1.8.0        (Windows XP SP3)
Uniform Server 8.5.8-Coral  (Windows XP SP3)

For details see:
http://forum.uniformserver.com/index.php?showtopic=2627&hl=

Windows 7 SP1 and Windows Server 2008 R2 (both is 64-bit OS)

I agree with above comment, it makes running PHP on a Windows production server impractical.

It seems happened since introduction of php 5.3.0. If you see in the changelogs:

http://www.php.net/ChangeLog-5.php

Added support for ACL (is_writable, is_readable, reports now correct results) on Windows. (Pierre,
Venkat Raman Don, Kanwaljeet Singla)

This issue is very critical, because it makes php running on windows production server impractical /
unusable...

My quad xeon box becomes very slow after some days, the ram usage is mysteriously increased (httpd
process usage still remains the same, I thought handle consumes kernel spaces)...

If your webserver servers 1 million request, then there will be about 1 million handle opened...
Usual application only consumes 20 to 2000 handles...

Description:
------------
PHP vc9 5.3.14, thread safe version + Apache Httpd 2.2.22 + Win 7/Win Server 2008 
R2

Each time is_readable in invoked, it leaves an open handle in the httpd process.



Test script:
---------------
for($i=0; $i<100;$i++) {
  is_readable("c:\\temp");
}

NOTE: the folder/file must exist for the leak to happen.

Expected result:
----------------
No leaked handles

Actual result:
--------------
100 leaked handles
