1. Open attached score.
2. Double-click note (entering 'edit mode').
3. Click on the score (exiting 'edit mode').
4. 'Play' immediately and repeatedly.

Result: Crash.

Discussion: Sometimes you don't have to click repeatedly, it'll just crash if you stop playback.

Comments

Persistence maybe required for this somewhat difficult-to-reproduce crash. I managed in 5511, but am now struggling.

It could be the answer as to why crashes occur when stopping playback. I wonder if it's something to do with the soundfont, and if it's connected to this: #13528: Closing score during load of navigator pages causes crash

I attach a crash log from a previous version (5483), when I managed to reproduce (using another score).

According to this last log, it's a crash in the synth

7 libportaudio.2.dylib 0x05439e7c PaMacCore_Initialize + 9852

This is apparently another way to reproduce with the same result (can't remember exactly, but these maybe the steps):

1. Open score.
2. 'Mixer'
3. 'Play'.
4. Change sound.
5. 'Stop'.

Result: Crash.
