Well, I know almost nothing about DSP, but for sure, there is nothing to
prevent any crash. My waldorf (Q) crashed once in a week (based on
56303, as most hardware VA theses days, including nova and virus). The
thing is that generally, the system is a lot more simple on DSP based
machines, so it is simpler to 'control everything'.
But my point may be too naive !
