In the PHP 4.3.11 under the same server with the same test request =
200 OK.
So this bug is PHP5.1 specific.

The way to reproduce:
GET /php.php5 HTTP/1.0
Host: localhost
Cookie: phpbb2mysql_data=a%3A0%3A%7B%7D;
phpbb2mysql_data=a%3A0%3A%7B%7D
Connection: close
Posted this request (via telnet) to my local web-server and got the
same error! (the script php.php5 just "echo 'test'"). PHP has
encountered an Access Violation at 00F2813A
If I delete second variable copy, i.e.:
GET /php.php5 HTTP/1.0
Host: localhost
Cookie: phpbb2mysql_data=a%3A0%3A%7B%7D
Connection: close
- the script works ok.

Description:
------------
Just downloaded and installed 5.1 snap (2 Aug) and replaced PHP5.1b3 in
my server (ISAPI mode). Now I see in log, some users got "error 500"
while accessing /forum/ and /forum/viewtopic.php (PhpBB current
version). Turn on trace and get error pages:
Mon, 01 Aug 2005 20:48:52 -0500 www.mdaemon.ru/forum/
HTTP/1.0 500 Internal Server Error
Content-Type: text/html
PHP has encountered an Access Violation at 00F9813A
Mon, 01 Aug 2005 20:48:54 -0500 www.mdaemon.ru/forum/
HTTP/1.0 500 Internal Server Error
Content-Type: text/html
PHP has encountered an Access Violation at 00F9813A
After server restart - address changed:
PHP has encountered an Access Violation at 0109813A
Reproduce code:
---------------
I can't reproduce it myself (same pages loaded ok), but there are lot
of such dumps in my log. I can install and try any test version there.
Expected result:
----------------
Page load.
Actual result:
--------------
PHP has encountered an Access Violation at 0109813A
------------------------------------------------------------------------
