Summary0009364: Removing tracks with a connected input or disconnecting the input will often crash if _GLIBCXX_ASSERTIONS is defined
DescriptionOn a binary built with the _GLIBCXX_ASSERTIONS macro set (e.g. the Fedora RPM package of 7.4.0, a local build from git with `./waf configure ... --arch="-Wp,-D_GLIBCXX_ASSERTIONS"`), Ardour very often crashes if I remove a track with a connected input, or if I attempt to disconnect the input.
Steps To Reproduce1. Build Ardour with _GLIBCXX_ASSERTIONS defined
2. Start Ardour with an empty session
3. Add a track and ensure its input is connected (doesn’t matter if Audio or MIDI track, the latter e.g. connected to the virtual keyboard)
4.1. Right click on the track header in the editor and select "Remove", confirm removal, _or_
4.2. Click the input button in the mixer and select "Disconnect"
Additional InformationRunning Ardour with --gdb set, I get this when removing a track causes it to crash …:
