PHP Bug Type: COM related
Bug description: COM functionality broken in PHP 4.3.10
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.
