Steps to reproduce:
- Open Audacity
- Open new Audacity window via Ctrl+N or Ctrl+O
- Add new stereo track in both windows (so Audacity will not quit silently)
- Quit Audacity from the first window (via menu or Ctrl+Q)
- Select “No” to discard the project for the first window
- Select “Cancel” to not close for the second window
- Segfault
The issue doesn’t reproduce if one quits Audacity from the second window.
Environment: Arch Linux, Xfce, Audacity 3.7.7
I am attaching Audacity generated dbgrpt and coredump.
