PHP has encountered an Access Violation at <address that changes>

Am running Windows Server 2003 SP1/IIS6 and PHP 5.0.5 as ISAPI filter without any problems. Upgraded to 5.1.1 and within 2-3 page views I start getting error "PHP has encountered an Access Violation at <address that changes>" in my PHP pages and on the console of the server an error is generated about a IIS worker thread has failed.

I roll back to PHP 5.0.5 and everything work perfectly again. I have repeated the upgrade and rollback numerous times with exact same results.

Only extensions I have enabled are: php_gd2.dll, php_mbstring.dll and php_mysql.dll

Reproduce code:
---------------
<?PHP
phpinfo();
?>


Expected result:
----------------
PHPInfo page results

Actual result:
--------------
Works 2-3 times and then I start getting "PHP has encountered an Access Violation at <address that changes>"
