Timings for some interesting instructions

Windows Defender thinks the .exe is a "severe" threat and has quarantined it. Without any source code who knows.

The archive contains the source. So you know (if you understand assembler code, of course)

[quarantined]

More important yet, running my code, you never know if it's working, or not!!!   

While running under 'normal' conditions it crashes. Viewing the code run in a debugger, it runs without flaw.
Therefore it seems it changes state simply by observing it.

Strange. What exactly happens? Which CPU, which OS version?
