Operating system: Windows Server 2003 Std. Ed. R2
PHP version: 5.1.4
PHP Bug Type: IIS related
Bug description: PHP crashes IIS worker process and application pool

Description:
------------
Hello, I see that other people have reported a similar bug, and that this
bug http://bugs.php.net/bug.php?id=35612 claims to be fixed. However, I
encounter a lot of trouble with PHP v5.1.4 (I haven't tried any other
version)

I feel like inserting error logs from the Windows Event log here, but I'm
trying to stick to what this web page is telling me - not to put any huge
text in this box.

What did I do? I installed a FRESH copy of Windows Server 2003 Std. Ed. R2
and PHP v5.1.4

Extensions that are loaded:
extension=php_mbstring.dll
extension=php_gd2.dll
extension=php_mssql.dll
extension=php_mysql.dll
extension=php_mysqli.dll

Sessions enabled
Browscap enabled

What did I expect? I expected PHP to work smootly on my system

What actually happened? PHP makes IIS worker process and the application
pool to terminate.

Do I know for a fact that PHP is causing the trouble? I do, because I've
run a debugging tool called IIS Diagonstics, and it has traced the problem
to be php5ts.dll

Also, the error was not there before I installed PHP. If I unload the
php5isapi.dll from the IIS server the problem is gone.

See the bug report here:
http://eventlog.no/php/IIS_Report__Date_07_14_2006__Time_11_41_51AM__903.mht

Use Internet Explorer to open it (Sorry, don't know of any other way)

Don't get me wrong. I love PHP, but it would be great if this error was
solved, if possible :-)

Please get back to me if you want the event logs from Windows

Reproduce code:
---------------
There is no specific code that reproduces this error. Only the fact that
PHP is installed causes the problems

Expected result:
----------------
N/A

Actual result:
--------------
Two examples from windows event logs:
