Description:
------------
Previously the following script to monitor CPU usage on Windows was working with PHP 4.3.8.

The following script also fails with PHP 5.0.3.

Thanks for looking into it. John Lim.

Reproduce code:
---------------
<?php

error_reporting(E_ALL);

$c = new COM("WinMgmts:{impersonationLevel=impersonate}!Win32_PerfRawData_PerfOS_Processor.Name='_Total'");
if (!$c) return false;

$info[0] = $c->PercentProcessorTime;
$info[1] = $c->TimeStamp_Sys100NS;
print_r($info);

?>

Expected result:
----------------
TESTED ON PHP 4.3.8 works fine:

C:\php4\php438>php -n c:\com.php  
Content-type: text/html
X-Powered-By: PHP/4.3.8

Array
(
    [0] => 363738299988;
    [1] => 127513714771937472
)

Actual result:
--------------
Crash with no output and windows crash manager dialog box appears.
