Any sane compiler will simplify this into

    function cosmicRayDetector() {
      while(true) {
      }
    }

C++ may further 'simplify' this into

    function cosmicRayDetector() {
      return
    }

Iirc the issue was that while(true) would be removed while it should be replaced with ret and this caused a bug where the binary would execute next function

But I believe this way of cosmic ray detection would work

volatile bool condition = true;
while(condition) {
}
printf("Cosmic ray detected");
