> Are you sure you upgraded correctly and have no stale DLLs?
Yes. I can rule out, that there are any older DLLs in the %PATH% which
may be loaded earlier. From Apache I load the php4ts.dll giving the
complete path and at command-line there's no place where such a DLL
could hide.
Maybe it's the symptom of another change :-/
We are going to upgrade to PHP 5 anyway, but we'll have to review all
our scripts. Therefore we are still using 4.3.10.

The 4.3 COM codebase hasn't changed in the latest release, so this
sounds fishy.
Are you sure you upgraded correctly and have no stale DLLs?
If you continue to have COM related problems, we highly recommend that
you upgrade to PHP 5 where the COM support has been completely
rewritten.
We don't support COM in PHP 4 any longer (although you might be able to
sponsor one of the developers to work on it if you're really serious).

Description:
------------
When calling new COM() in PHP 4.3.10 the call will raise an exception
due to read of memory at a location too close to NULL (same memory
page).
This problem occurred only in the latest PHP release. It does not apply
to 4.3.9! Actually because it broke some of our scripts we recognized
this as a problem.
Reproduce code:
---------------
//---------------------------------------------------
function GetDomainMachines($DomainName)
{
// Get the domain object ...
$objDomain = new COM("WinNT://".$DomainName);
// List all objects and ...
while($obj = $objDomain->Next())
// ... filter for computers
if ($obj->Class == "Computer"){
$arr[] = $obj->Name;
}
return $arr;
}
/* Give a valid domain name as the parameter, then call
the function and dump the array contents */
Expected result:
----------------
It will return all machine names of domain members in the hash.
Instead of filtering for type "Computer" one may use "User" and give
the local machine as the "DomainName" parameter. In this case it should
even work on the local machine and will return all users of the local
machine.
Actual result:
--------------
Exception (messagebox, not even as a PHP error). Find a screenshot
here:

Note, that regardless which object you try to instantiate you'll always
fail reading at 0x0000006c, not different locations in memory.
