Playback of a score starting with a volta fails and leads to crash
2.3.1 version / Windows10
By working around this thread (https://musescore.org/en/node/274658), I found that the crash (when launching playback, or when pressing the "Rewind to the start position" button with this score: Miller Medley SCORE.mscz ) does not occur in early February 2018 before that several commits, concerning the improvements of the handling of voltas and repeats, were merged.
I can not reproduce from scratch from now.
However, without knowing whether this can be related, I notice an unexpected behavior (although the probability of this use case is near or equal to zero)
Therefore, from this test file ( volta1.mscz ) or that one ( volta1 (1).mscz ) with simple voltas, it is impossible that the playback starts at the beginning of the file with the measure including a volta. It begins obligatorily after, as if the measure with the volta was ignored.
I leave it to a minor priority for the moment being the probability of use.
