Summary0008008: Ardour crashes immediately on playback of old session
DescriptionIn 2008 (!) I recorded 6 tracks with Ardour. I’m now trying to open them again to do some remixing. Amazingly 5 of the 6 tracks open and I can play them back (great work on backwards compatibility!). The 6th has issues. I can open it and see audio, but any attempt to play the audio (whole session, soloed track, export) causes an immediate crash. I’ve attached the backtrace and save file. I’m happy to provide any additional information you need. Thanks for your hard work on this awesome project!

Please read http://ardour.org/debugging_ardour and see if you can an actual backtrace from gdb

Is there an "/opt/Ardour_<VERSION>/bin/ardour<N> --gdb" equivalent for OSX without building from source? If not I may grab a Linux machine.

Was that second backtrace complete? Or do you have any more debugging instructions for macOS?

The crash is in "AudioDiskstream::process" -- that function was meanwhile removed for upcoming Ardour 6.0.
So chances are that the issue may not longer be present.

I can confirm that upgrading to 6 fixed the problem, thanks!

Upgrading to 6 meant bug was no longer an issue in this case.
