vulnerability in… WinCalc (Win7, x64)

I will never go out of business in this country. thanks to Microsoft. who would have thought that wincalcis vulnerable? I have not checked all systems yet, so this is my configuration: Windows 7 Ultimate SP1 x86-64, English.

1) run calc.exe;
2) press “Alt-2″ to go to “Scientistic” mode (“Programmer” mode works too);
3) type “1/255″ and press [ENTER] or [=]
4) press the button [F-E];

ops! shit happens!
