@dan I honestly can't work out whether this was an elaborate troll.
It reminds me of debate about jitter on cd drives affecting sound quality (ignoring that resynchronising to an accurate clock is easy to do in hardware). Or eliminating negative feedback from audio amplifiers. Oh, and shaving the sides of cds. And many many more...

@briancs @dan myself I recall that this turned out to be a bug in Linux where the memory was getting corrupted by these calls

@mkf @dan bug or misuse. Memcpy() is explicitly documented to have undefined behaviour if copied regions overlap. You need memmove() if that is the case. I'd be truly astonished if a bug in memcpy() laid undiscovered for any length of time. Literally everything would be broken.

@briancs @dan that is a good basis for presuming my memory may wrong me, wouldn't be a rare occurence. i will sometime see back in my fedi boosts to find the thing i may have had misread and come back with it

@briancs @dan Anything to avoid replacing a broken wall wart or clock-recovery circut. Shaving the sides of CDs does make a diffeience when the player's power supply is dying (as the extra current drawn by the tracking system to compensate for wobble can brown out the logic), but replacing the power supply with a new one seems much easier than this "workaround".
