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)

kamilner 2026-01-27 13:55 reporter ~0029778	It seems much more reliable with Ardour-9.0.rc3.17-dbg but I have still got it to crash occasionally. I have to repeat the clip recording several times in order to get it to crash now, each time deleting the clip from the slots, re-arming them, and starting the clip recording again. I actually wonder if it has anything to do with parallel clip recording at all, and may be down to frequent clearing the slot and re-recording.

kamilner 2026-01-27 15:25 reporter ~0029782	I tried recording and then deleting the recorded clip in a single track multiple times with no crash. So I do think it has something to do with parallel recording. I have attached a core dump from Ardour-9.0.rc3.17-dbg, although I suspect that will be equally unhelpful.

paul 2026-01-27 21:52 administrator ~0029785	core dumps are almost never useful, only the backtraces from gdb ...

paul 2026-01-27 21:55 administrator ~0029786	also, backtraces from system faciliities tend to be similarly unhelpful, alas. this particular one looks different than the earlier report, however.

kamilner 2026-01-29 11:56 reporter ~0029788	Ardour nightly Ardour-9.0.rc5-dbg I attempted parallel recording again. Then cleared the slots of the clips I recorded and tried again and got another crash. Backtrace attached Ardour9 Crash data-2.txt (319,619 bytes)
