Even if trying to playback with ALSA or PulseAudio, mscore crashes.

Confirmed, Windows 7, not using Jack at all.

Somehow related to voltas and repeatlist, maybe something for @jeetee?

I'll have a look, playback works in 2.2 though, which uses pretty much identical code for that part (only change is toVolta vs static_cast<>).
Given the stack trace it seems that for some reason the endMeasure of one of the volta's in that score would be invalid (nullptr ?).
To be continued on an actual debug session…

The actual crash is in searchVolta#404 and it is caused by detecting a volta with an invalid startElement (the volta2 of the last measure). It is present in the mscx, but also not rendered by MS3.
See attached for a "fixed" file in which that volta has been removed. Later investigation is required to figure out if MS3 simply has issues with voltas on last measures?
