Description:
------------
IIS 6 with PHP 5 SAPI:

In some cases, the CWD of a PHP-script run is not properly reset to the script's directory. Its instead the directory of another previously run script.

chdir() with an absulote path fails in these cases if the desired path is no child of the script's path itself, while chdir() with a relative path to the same destination succeedes.

Reproduce code:
---------------
Script located in d:\webshare\web3

echo '<div>CWD is '.getcwd().'</div>';
chdir( 'd:\\webshare\\web3' );
echo '<div>CWD is '.getcwd().'</div>';
chdir( 'd:\\webshare\\web3\\test' );
echo '<div>CWD is '.getcwd().'</div>';

Expected result:
----------------
Script located in d:\webshare\web3

CWD is 'd:\webshare\web3'
CWD is 'd:\webshare\web3'
CWD is 'd:\webshare\web3\test'

Actual result:
--------------
Script located in d:\webshare\web3

CWD is 'd:\webshare\another\scripts\path'
Warning: chdir() [function.chdir]: No such file or directory (errno 2) in D:\webshare\web3\test.php on line 4
CWD is 'd:\webshare\another\scripts\path'
CWD is 'd:\webshare\web3\test'

-- or sometimes --

Script located in d:\webshare\web3

CWD is 'd:\webshare\another\scripts\path'
Warning: chdir() [function.chdir]: No error (errno 0) in D:\webshare\web3\test.php on line 4
CWD is 'd:\webshare\another\scripts\path'
CWD is 'd:\webshare\web3\test'

I checked it with php 5.2.5 and 5.2.6 + IIS + Win 2003 Server SP1.
Same error on both versions, I even can't include files because of this.

include(config.php) [function.include]: failed to open stream: No such file or directory

config.php is in the same directory and has same rights than the calling index.php.

getcwd, placed on top of index.php shows me everytime I run this script another dir out of the docroot. chdir(basename(__FILE__)) under/above getcwd fails with error 0 like in this bugreport.

We are aware of PHP's problems with stability under IIS and are working 
to rectify the problem. Unfortunatly your bug report does not contain any
extra useful information and we already have enough bug reports open about
this issue. If you can provide more detailed information such as a 
reproducable crash or a backtrace please do so and reopen this bug. 
Otherwise please keep trying new releases as we are working to resolve 
the problems on this platform
 
Thanks for your interest in PHP.

I am using XAMPP and I just got the "No error(errno 0)" error on an attempt to change directory to /var/www/a_misspelled_dirname.  The error should have been No such file or directory (errno 2).  I thought this info might be useful, as I'm not using IIS at all.
