Summary0009283: ardour crashes on session load
DescriptionHi! The Ardour 7.3.0 official build recently started crashing on this session, and this session only, whether plugins are enabled or not. This was preceded by some crashing happening when zooming in and moving newly-combined regions on five or six tracks at once, and recovering crash data following those crashes. Thanks!
Steps To ReproduceOpening this file.
Additional InformationI've tried to attach a backtrace here. The session file is larger than the upload limit; here's a link to it: https://drive.google.com/file/d/1MZiqd721lBUsWh2u7gwdriIW_3jocSpj/view?usp=sharing

When run from the command line, Ardour reports this right before crashing:

ardour-7.3.67: ../libs/ardour/audio_playlist.cc:279: ARDOUR::timecnt_t ARDOUR::AudioPlaylist::read(ARDOUR::Sample*, ARDOUR::Sample*, float*, const timepos_t&, const timecnt_t&, uint32_t): Assertion `start.distance (i->range.start()).samples() + read_cnt <= scnt' failed.

Can you attach the session (as an archive) ?

Somehow didn't think to zip the file. Thanks so much!

I will need the entire session (Session > Archive), not just the .ardour file ...

Oh, I think I see. It's a 1.3GB file, so here's a link to it. If I'm still misunderstanding, please just let me know.

OK fixed. You can get the corrected session file at https://ardour.org/files/defamation.ardour

The error was caused by mixed time domains in the length of many regions in this session. It would be a good idea for us to figure out how this happened, but I'm not sure how easy that might be.

Also, what system do you run this on? It was overloading on my 16 core Ryzen Threadripper ...

Paul, thanks so much for this! I can't overstate how well-supported I feel right now. You're the best!

I'm running on a dell tower system with an i7-12700K, 16GB RAM, and and RME Raydat. I think it's the first desktop computer I've ever had that's fairly current in specs. I'd been wanting an RME interface since I first read about them on the LAU list years ago - might be a stretch to say that I could finally afford one, but I did finally buy one. :)
