MuseScore

Load MuseScore.
Open attached score.
'Play' and 'Stop' immediately.
Drag score around (e.g. using scrolling wheel) for a few seconds.

Result: Crash (see attached log).

Note: I sometimes managed to reproduce using other methods, such as holding spacebar, or clicking a note.

Using MuseScore 3.0 Nightly 6a015b8 - Mac 10.11.6.

See another crash issue pertaining to soundfont load, though seemingly unlike the one above it can be reproduced in both 2.x and 3.x: #273783: Crash when playing and closing score whilst synthesiser loads

Even just playing and stopping during soundfont load results in a crash (similar log?).

Maybe this should be upgraded to Always?

Using MuseScore 3.1 custom build f86361c - Mac 10.11.6.

Unfortunately the log file under the link does not exist.
But that looks exactly like one of the most often crashes we receive crash reports about (a typical call stack is attached). Users wrote in those reports that they tried to play a score or started the playback and stopped it before it had actually started. So that's good that we actually have precise steps to reproduce the issue. I'll mark this issue P0, given that it affects many people, it is important to address it in the next releases.
