Description:
------------
Multiple calls to a COM function result in crash / memory corruption / weird behaviour.

Test script:
---------------
$ php -r '$com= new com("winmgmts:"); foreach (explode(",", $argv[1]) as
$pid) { $p= $com->get("//./root/cimv2:Win32_Process.Handle=$pid"); echo $pid, ":
", $p->executablePath, ": "; var_dump($p->commandLine); }' 3132,2760,3268

Expected result:
----------------
Something like:
3132: C:\...\GoogleToolbarNotifier.exe: string(74)
""C:\...\GoogleToolbarNotifier.exe" "
2760: F:\...\ONENOTEM.EXE: string(58) ""F:\...\ONENOTEM.EXE" /tsr"
3268: F:\...\XWin.exe: string(38) "F:\...\XWin.exe :0 -multiwindow"

Actual result:
--------------
Something like:
3132: C:\...\GoogleToolbarNotifier.exe: string(74)
""C:\...\GoogleToolbarNotifier.exe" "
3132: C:\...\GoogleToolbarNotifier.exe: string(74)
""C:\...\GoogleToolbarNotifier.exe" "
3132: C:\...\GoogleToolbarNotifier.exe: string(74)
""C:\...\GoogleToolbarNotifier.exe" "
