Hmm, I'd guess that it might impact something that is different between different compilers and the like - timing on when the different code runs. Eg. One memcpy sometimes runs faster than other times, leading to distortion on the music. I imagine there's lots of built in tools that minimize said distortion by buffering, but if your buffered data is just barely keeping up with what's playing, a slightly slower copy could leaver the buffer empty for a moment
