MuseScore development builds crash when placing note

[faskr]

I have been working on a cloned repo of MuseScore on Ubuntu 22.04, but recently I started having a problem that I didn't have before. Any build that I run crashes when a new note is placed on a score. I even tried re-cloning but the same thing happened. There seems to be something wrong with my system but all required packages that I could find are installed. I don't think it has to do with MuseScore updates either, because complete builds that worked before started crashing too. Here's the output:

I don't think this is reproducible from what I know currently, but my system is Ubuntu 22.04, and I simply opened a new score, entered note placing mode, and placed a note. I tested the latest development push, but as I said, builds from prior pushes that had worked suddenly had the same problem even though I hadn't rebuilt them.

[Jojo-Schmitz]

So it dies of a failed assertion in https://github.com/musescore/MuseScore/blob/master/thirdparty/opus/celt/celt_decoder.c#L118

[Jojo-Schmitz]

Maybe don't build in Debug mode?

[lyrra]

Can't reproduce it. Though it's strange how a note-input can cause a crash in opus. Since opus is used during export to ogg.

[faskr]

Maybe don't build in Debug mode?

It crashes in both Debug and Release.

[Jojo-Schmitz]

Strange, asserts should be disabled in non-Debug builds

[faskr]

I found out that besides the above case, it crashes when opening any score with notes that is produced by MuseScore 4, but there's no problem with scores from MuseScore 3.

[faskr]

I got the MuseScore build to run fine on a VM without this problem but on my host system for whatever reason it's still happening.

@faskr Given that you can build MuseScore yourself, does that also mean you can run it in a debugger? It would be useful to see the stack trace (rather than the console output).

This is the call stack when MS4 pauses on exception as soon as a note is placed:

Thanks! That's useful. So this is a Muse Sounds issue...

[Blargian]

I'd like to add to this that I seem to be running into the same issue while trying to select a new sound from the mixer while running Debug (from master branch) on Ubuntu 22.04.2. The only other instruments pack I have besides MuseBasic is MuseBrass. When selecting a MuseBrass instrument the program crashes with a segfault. This bug is not reproducible for me in the 4.0.2 release.

Application output:

I have exactly the same on my 4.1 build on Ubuntu 22.04 (vst enabled), when selecting a MuseSounds instrument in the mixer.
(VST gui works in some cases with Linux VST's, in all cases with Windows VST's + yabridge, e.g. BBCSO, Miroslav, Kontakt)
