I tried to remove and reinstall it, same result. Fasttracker 2 clone is stil working, so I'll use that or get old Ubuntu version in Virtualbox and use Milkytracker in Ubuntu 23.04 LTS. :D

Using the disassembler we learn that 0x000055555557c3e6 actually calls operator delete in the vicinity of a few calls to std::basic_string<...>::_M_dispose(). Further investigation hints on these two functions:

Difficult to tell whether this is a bug in Milkytracker or RTMidi. You could try updating RTMidi to the latest version and see if that fixes things. Also a debug build would generate more useful backtraces.

[maranemil]

I don't how to debug. Installing Milkytracker with cmake from github seems to work, following the Install.md instructions.

sudo apt install cmake -y
sudo apt install git -y
sudo apt-get install build-essential -y
sudo apt-get install libjack-dev liblhasa-dev librtmidi-dev libsdl2-dev libzzip-dev

cd ~
mkdir Git && cd Git
git clone https://github.com/milkytracker/MilkyTracker.git
cd MilkyTracker
mkdir build
cd build
cmake ..
make
~/Git/MilkyTracker/build/src/tracker/milkytracker 

Searching in apt list gives the same version v1.04.00 back

apt search milky
Sortierung… Fertig
Volltextsuche… Fertig
milkytracker/mantic,now 1.04.00+dfsg-1 amd64  [installiert]
  Werkzeug zur Erstellung von Musik, inspiriert von Fast Tracker 2

The one installed by apt does not work. The one installed by cmake works. :D

Ubuntu 23.04 had the v1.03.00 , that's why it worked before upgrade to Ubuntu 23.10.

I think this is the same issue as #320. Unfortunately Ubuntu 23.10 shipped the broken version of 1.04 using the git tag instead of the version on the GitHub release page. I uploaded the fixed version a few weeks ago so it will be fixed in 24.04. The called the fixed version "1.04.00.20230830+dfsg-1".

You can get it here if you want: https://launchpad.net/ubuntu/+source/milkytracker Click the arrow next to "Noble" and download the debs.

Fixing it in 23.10 requires going through this: https://wiki.ubuntu.com/StableReleaseUpdates, but I don't have time to do that at the moment.

at least works after compiled
