Summary	0008757: Ardour crashing
Description	Sudden crashes where Ardour abruptly exits with no error message
Steps To Reproduce	Open existing project Import file(s) to new tracks Solo new track, start playback from start / home of track Do multiple placements of playhead while playing back (to find the correct edit point) Crash happens here, or sometimes after I repeat the procedure with another track. Possibly after small edits like cutting and moving regions between tracks. Not sure since the crash is 'sometimes'. After crash Studio controls show a count of several xruns
Additional Information	On next start, Ardour is aware of the crash: "This session appears to have been modified without save, or in middle of recording when Ardour or the computer was shutdown" This is followed by a choice whether to "ignore crash data" or "Recover from crash"
Tags	6.7, 6.8, Editor, Import

Hans Flikkema 2021-06-24 16:49 reporter ~0026004	Hi I have the same problems with Ardour 6.7 running on W10. I tried 6.7.0, 6.7.12 and 6.7.52 They all crash after one tot 10 minutes, with no recovery, no messages when I open existing projects. All these projects run smoothly without any problems using 6.6.346 and 6.5.51 I have to finish 2 important projects in the next 2 month so I re installed 6.6.346 I'm getting a bit worried for 6.5.0, also a official release had also major issues. I had to wiat for nightly build version 5.5.50 for smooth runnings.

al f 2021-07-20 12:54 reporter ~0026066	I have been experiencing crashes with Ardour 6.8 as well. I am editing an interview which means extensive splitting, combining and moving of regions. I believe my work is not heavy on resources as the audio lasts less than an hour and I am working with at most three tracks (hardware is 32 GB RAM with an Intel Core i7 processor). There is a sudden burst of xruns (or the crash causes them, I can't determine which) and Ardour just exits without any message. I am not sure how to reproduce the crash, but it happens often - four or five times today during some two or three hours of editing. The crash changes at least one setting: on restart of Ardour, the transport does not follow the playhead and I have to manually set Transport > Folllow Playhead. Thankfully, there is usually not much work lost, partly because of saving frequently and partly because Ardours "recover from crash" option at restart leaves out just the few last operations.

al f 2021-07-20 12:57 reporter ~0026067	Also, the interview files are directly recorded into Ardour, not imported as the tag from my original post implies.

al f 2021-07-21 06:10 reporter ~0026068	I've been reading https://ardour.org/debugging_ardour and understand I should provide a backtrace. The guide tells me to use gdb, directing me to https://www.gnu.org/software/gdb/ for downloading. I would prefer running something from the repositories of my (K)Ubuntu Studio install. Could I get some pointer for that, or is gdb required?

al f 2021-07-21 11:33 reporter ~0026069	From the debugging guide I followed option 2, typing $ ulimit -c unlimited after which i started Ardour I did NOT download Ardour with debugging symbols (if that's a requirement, let me know). The core dump is more than 600 MB and can't be uploaded here, so I put it at https://mega.nz/folder/NThzWCAJ#hBluhOmOunCziKDUfpKDvA Do I need to "undo" ulimit -c unlimited - if so, how?

al f 2021-07-21 15:38 reporter ~0026071	I uploaded two new core dumps to the location given above. On both occasions Ardour crashed when scrolling in the navigation field at the bottom of the scren to zoom in for editing.

al f 2021-07-21 21:01 reporter ~0026072	These crashes does not seem to happen with Ardour 6.6, which I've been running for the last few hours. I've been using the new "Region Cue Markers" extensively, otherwise I don't think I'm using functions in 6.8 not present in 6.6. Sorry if I'm posting too many times here...

al f 2021-07-22 20:34 reporter ~0026073	After reading the reporting guide more closely, I see I didn't do it right. Attached here is the log from gdb, hope I got it right this time...

paul 2021-07-22 21:42 administrator ~0026074	It would be (more) useful if you could get a backtrace from a build with debugging symbols. This doesn't offer much context. Also, some clue about what you were doing when the crash happened. If we can't reproduce it, it's hard to fix it.

al f 2021-07-22 21:55 reporter ~0026075	Is there a binary with debugging symbols, or dpo I have to bulid? I am editing when the crash happens: splitting, cutting, moving and combining regions. Also removing or inserting time and using / editing markers, both normal markers on the timeline and the newer region cue markers. I am quite sure the crash does not happen at the same action each time. Sometimes it will be after closing one session and opening the next, other times when moving a region or opening the menu to insert or remove time. I also experience strange and erratic behaviour when inserting time (it is inserted at some random place to the left of the edit point (I am considering a separate bug report for this, though I have a feeling they have the same cause). When crashing there are multiiple xruns counted by studio controls, but I haven't been able to determine if the xruns are caused by the crash or causing it.

paul 2021-07-22 22:12 administrator ~0026076	You can grab one from nightly.ardour.org (there are free/demo copies which are fine for this purpose. They can be installed in parallel with any other version of Ardour whether from ardour.org or a distro. xruns do not cause crashes.

al f 2021-07-26 11:26 reporter ~0026080	I also got crashes on SCROLL-TO-ZOOM in the navigator panel at the bottom of the screen. I reproduced the crash by splitting a region in track 2, moving the left part of the split region to track 1 (drag and drop) and then using the scroll wheel (UP) to zoom in for editing. Attached here is the gdb output for that. gdb-ardour-06-scroll-to-zoom.txt (58,039 bytes) Starting program: /opt/Ardour-6.8.209-dbg/bin/ardour-6.8.209 [Thread debugging using libthread_db enabled] Using host libthread_db library "/lib/x86_64-linux-gnu/libthread_db.so.1".

paul 2021-07-26 13:51 administrator ~0026082	You had already used some region cue markers?

al f 2021-07-26 14:47 reporter ~0026083	Yes, I've used a few - less than five I think (I am away from session right now, so can't check exact number [is there a way to do that?])

al f 2021-08-01 09:54 reporter ~0026085	I was working on a new session that didn't have any crashing problems, when I added some region cue markers and removed one track. The removed track was empty. After that, Ardour started crashing on navigation in the summary (navigation bar at the bottom of the screen). I'm adding the debug info from reproducing the crash. I'm no programmer, but it seems to me that that introducing region cue markers to the session induced the crashes. gdb-ardour-06.txt (57,922 bytes) Starting program: /opt/Ardour-6.8.209-dbg/bin/ardour-6.8.209 [Thread debugging using libthread_db enabled] Using host libthread_db library "/lib/x86_64-linux-gnu/libthread_db.so.1".

al f 2021-08-01 10:06 reporter ~0026086	Some regions containing cue markers were moved or deleted, or trimmed so that the cue markers were not visible anymore. It seems to me that these steps will reproduce crashes: 1. start using region cue marks (I am naming them like "N some text" where N is a number. The text may contain ! or ? or . 2. moving along the timeline using the summary, setting cue markers and splitting, trimming, moving, cutting and pasting regions as needed. 3. Ardour will eventually crash on "click and drag" or "scroll" when the mouse pointer is in the summary.

paul 2021-08-03 18:56 administrator ~0026088	this is now fixed as of commit b8bb5e6bd15eb0 Thanks for your help with this.

al f 2021-08-06 19:00 reporter ~0026091	Wonderful news - thanks a lot for the effort and for a fantastic piece of software!

al f 2021-08-07 12:23 reporter ~0026095	What does this mean for when the fix will be available - will there be a 6.9 release or should I wait for 7.0?

paul 2021-08-07 14:09 administrator ~0026097	You could pick up a nightly build from nightly.ardour.org if you're a subscriber or paid at least US$45 for ardour from ardour.org
