Summary	0010138: Parallel recording of clips with different record lengths often causes crash
Description	Ardour-9.0.rc3.8-dbg It is possible to record clips in two separate tracks at the same time. these can have different record lengths. Sometimes this works but, often, it causes a crash.
Steps To Reproduce	1. create new session with two MIDI clip tracks 2. In Clip view, arm both tracks to record 3. Connect both tracks to an appropriate MIDI input 4. In track 1, select a clip and arm it to record, set the record length to 4 bars 5. In track 2, select a clip and arm it to record, set the record length to 8 bars 6. Press space to start recording, record 8 bars of MIDI
Additional Information	Debug version crash report attached.
Tags	No tags attached.

paul 2026-01-26 18:03 administrator ~0029772	hmm, works fine here with 9.0-rc3-10-g4071ade443

paul 2026-01-26 18:42 administrator ~0029773	the crash occured during building a new SMF (file) from the captured data, when there was an attempt to append an event that was earlier than the previous one. not sure how this can happen. if you can reliably reproduce it, i can think about how we could debug it, but i suspect it may not be reproduceable (though this bug reports hints the opposite)
