We are using PHP 4.1.2 on IIS 5.0 on Windows 2000.
PHP is running in ISAPI mode. We use to have Memory Access Violation in PHP 4.1.0, but the problem disappeared in version 4.1.1. We replace the version 4.1.1 by 4.1.2 this morning, and without changing anything else, we are getting Memory Access Violation every other pages. We are forced to go back to version 4.1.1

Hi,

Could you provide some information for us to work from? eg, what script in particular (if any) is causing this, and also some information on your environment.

it doesn't crash for me.

I have the exact same configuration.
I just installed PHP 4.1.2 to work with the ISAPI module.
When I visit ANY php page it gives the following error msg: "Invalid access to memory location."
The CGI module still works ok.
I was looking for version 4.1.1 to test if this one works, but it is not available on php.net any more. Could someone provide me a link to 4.1.1, so that I can see if it works with that one.

Just tried it with php 4.0.6 (allthough phpinfo() says 4.0.5) and everything works fine.
btw it's Windows 2000 Server that I use.

The problem appears on any page. The only constant is that every page is connecting to a database (MS SQL Server) using DB::connect

After trying different configurations, it seems that the problem appears when using Zend Optimizer. I reinstalled PHP 4.12 and removed the option Zend Optimizer in the php.ini and it seems to work now. The solution works, but I definitely need to use the optimizer as I want to Zend Encode my pages.

Please report Zend Optimizer bugs to Zend people.
www.zend.com ? This is mentioned in their FAQs somewhere too.
