Hi

When trying to export an mp3 with musescore 4.0-1 (manjaro version) on Linux, this is what I see in the logs:

20:43:15.793 | INFO  | 140475688281792 | MuseSamplerWrapper | flushSound: ALL NOTES OFF
malloc(): invalid next size (unsorted)
[1]    2232217 IOT instruction (core dumped)  mscore

The generated file will be 0 bytes.

Settings:
* Format mp3
* Sample rate 48kk
* 256 kbit/s

4.0, not 4.x-dev (but there's no such version here yet)

OS:

$ cat /etc/lsb-release 
DISTRIB_ID=ManjaroLinux
DISTRIB_RELEASE=22.0.0
DISTRIB_CODENAME=Sikaris
DISTRIB_DESCRIPTION="Manjaro Linux"

Further details:
* Logs attached
* .log files are not allowed, renamed console output to .log.txt.
* I noticed this error message:

(mscore:2232217): Gtk-WARNING **: 20:43:02.652: Failed to measure available space: The specified location is not supported

I am trying to save to a nextcloud folder, but that should be transparent to the app.

// edit: formating. Found out there is hidden code formating when using backticks. Much easier to read.

Not attaching original score b/c of copyright. But it crashes on ANY score.

Steps to reproduce:
* I use Manjaro (rolling release). I use btrfs partitions.
* Install package MuseScore from community
* I also installed muse-hub-bin from aur which extracts the files from the official .deb package
* I symlinked /srv/muse-hub to /home/muse-hub because of space constraints.
* Started MuseScore. Playback anything (any score) with Muse Sounds works fine.
* Click on export and chose any audio format. It will crash.

I can attach the core if you are interested in it.

Hey @Marc Sabatella!
I was able to reproduce it on my other Manjaro Machine which does not need Symlinking from /srv/ to any other folder.
There's only a minor difference. Other difference: Kernel 6.1 instead of 6.0.

The progress meter on my laptop can progress to 4% before it crashes. But there's still a 0 byte audio file written.

Interestingly, the malloc has a slightly different message:

free(): invalid pointer
[1]    3630 IOT instruction (core dumped)  mscore

instead of:

malloc(): invalid next size (unsorted)
[1] 2232217 IOT instruction (core dumped) mscore
