Satnam Singh, Senior MS Researcher, has published an F# program demoing Accelerator executing code on a 8-core 64-bit Windows 7 machine in addition to a low-end graphics card.

The recompiled code works fine on any Windows 7 SP1 machine, but mysteriously crashes on the Windows XP machines that have been running the program for nearly a decade.

You can look at the generated machine code and see that there's a chunk of your program missing.
