I created a script like this:

<?php
$adodb = new COM("ADODB.Connection");
?>

Each time I try to load this page I experience a "[snip] Memory could not be read" error with php.exe.  This happens with all COM objects, not just ADODB.Connection.

I have found this error with PHP 4.3.0 and 4.3.1, both using the PHP CGI module. cgi.force_redirect is set to "0".  All other normal pages run without a hitch. I have not changed the php.ini COM defaults in any way.  I do not use any extensions, and I am using the standard win32 binaries from php.net.
