I mean in theory different versions of memcpy could result in different EMI emissions which could get picked up by various analog paths. It's not as crazy as gold plated optical cables. Not really a problem today, but back when everyone had soundcards, EMI could definately screw with your audio if your PC wasn't built correctly. Probably a worse problem for those who didn't plug in their computer into a grounded outlet as well. I've definately heard hums in computer audio stemming from EMI when the computer is doing something heavy. Granted that was back when having your cellphone near your PC screwed with the sound when someone was calling.
