Summary0010099: Crash when cue clip is triggered
DescriptionI have a session saved where simply starting the transport causes a crash once a cue marker is passed. Before this I had saved the session while it was playing, which seemed to the start of the reproducible crashing state.
Steps To ReproduceI'm not sure how to reproduce it from a new session yet. I have a session archive that shows the issue though by simply pressing play, if needed.
Additional InformationI tried running ardour with --gdb but after the crash the UI disappears, and when I run "thread apply all bt" in gdb I get no output.

The issue goes away when I simply move the playhead to the beginning of the song. I've seen crashes before that seem to revolve around saving while playing so I expect the issue isn't "resolved" but temporarily worked around.

Can you attach an archive of the session folder?

Attached. I removed a bunch of audio sources to make it smaller but it still reproduces the issue for me when I hit play.
