I think this may be a bug. Can someone verify my findings?

Using the following code;
 Code:
? @kix
? iif(@onwow64,"64","32") + "bit"
? "Wow64FileRedirection=" + SETOPTION("Wow64FileRedirection")

;$rc=SETOPTION("Wow64FileRedirection","off")
$PID=EnumProcess("calc.exe")
? "PID=" + $Pid


Results:
 Code:
4.61 Beta 1
64bit
Wow64FileRedirection=OFF
PID=3952


Works as expected. However, just uncommenting the Wow64FileRedirection line, which should be doing nothing, as it is already OFF, breaks Enumprocess resulting in the following:

 Code:
4.61 Beta 1
64bit
Wow64FileRedirection=OFFselect * from Win32_Process where Name='calc.exe'
PID=


Tested with 4.53, 4.60, and 4.61b1 with the same results.
