Hey Cyril,
I think I finally understand what you mean by this now; it is rather
strange that the volatility of D does not protect loop from being
optimized away by the compiler.  I don't have a good explanation as to
why it's happening but I'm not sure how to evaluate what's going on
either.  Should I do anything to move this patch forward?

Thanks,
Edward
