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:


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

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


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

    [0] => 363738299988;
    [1] => 127513714771937472

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