This was actually observed in byuu v115 but I did not see it in the Closed Issues history so suspect it's still active.
Loading a save state in byuu v115, then attempting to rewind beyond the start position of the savestate, frequently but not always causes freezes and CTDs. I've been unable to discern a pattern but it seems more likely during rapid savestate loading followed by repeated rewinds, OR savestate load, waiting a long period of time, then rewinding as far back as allowed. No CTDs observed in the absence of savestate loading.
