Ardour 7 + crash at session loading

[Nomys_Tempar]

Hi! I have a session crashing with this message :

This is on 7.3. I was in 7.2 then I got a segmentation fault, so I decided to update to see if the session loads again (it did not).

The terminale give me a bunch of warning regarding lilv_plugin_get_name() but I don’t think that’s the issue here. I can post the complete log if needed.

Good morning
I also have a problem with 7.3. It hangs at startup on scanning vst3 plugins.

Im using MX AVL 21.3. Ardour 7.2 is working ok on the machine

[Nomys_Tempar]

@merryl0 You should open a new topic and post a loading log, because it doesn’t seem to be the same problem as mine…

[merryl0]

Thanks. That’s good advice. I wondered why I didn’t get any replies. Doh!
I just didnt want to start more new topics if it already existed, but now i get it.
The good news is; I went to bandshed, downloaded all the plugins and installed, then installed all the lsp plugins and now 7.3 starts!

[Nomys_Tempar]

I still have a segmentation fault in some cases (like trying to launch a backup).
The session crashes after the loading phase (If I press “space” I can briefly ear some sounds as it plays)

jack send this:

CheckRes error
Could not write notification
ClientNotify fails name = ardour notification = 10 val1 = 231 val2 = 0
Cannot write socket fd = 28 err = Broken pipe

My other sessions work fine.

I run gdb and got this:

I tried with the -B option (does it disable all plugins ? I’m not sure).
Anyway pretty much the same result:

I will open a bug report into the bug tracker, since I’m not getting much help here.

[Nomys_Tempar]

Ok I can’t submit a bug report because I keep getting a 401 error, even if I fill all fields (mostly this error seems about description, steps to reproduce and additional infos fields).

With the lack of responses here, this situation is really annoying.

Am I doing something wrong here ?

[seablade]

Nope but it could be no one has an idea yet what could be causing this. I am on my phone right now but iirc this happened in waveform drawing in the log you post so you could try deleting the peak files (they will be recreated) and see if that helps. Really the next step is likely what you were trying to do which is create a bug report and attach the session that isn’t working to see if it can be reproduced or not.

Convolver::reconfigure Nin=2 Nout=2 Nimp=4 Nchn=4

The above info suggests you may have run into the same problem as mentioned here

Determine "bad" plugin

It would seem you are using an ancient version of my convo.lv2, and a not optimized debug build of that as well. If you use multiple instances of that plugin, you may run into the old FFT concurrency issue. The official binary [1] is not affected by this, but depending on FFTW configuration Linux distribution or custom builds might be and result in a deadlock. [1] x42 Zero Config|Latency Convolver

[x42 (Robin Gareus)]

The issue is caused by the convolver plugin. The debug version that prints all this output is not safe to be used in production. Preferably get an optimized build (which is the default), it seems you have compiled it and disabled optimizations.

It also looks like you use an old version. And earlier version had a bug that caused issues when multiple instances were used in the same session. I am sorry, that I screwed up and that bug was there for a few months, but that was resolved quickly last year.

See the link that @peder referenced above.

[Nomys_Tempar]

@seablade Thanks for your answer. I can’t upload the session file on the bug tracker (file is too heavy).
Deleting peaks files doesn’t work.

@peder @x42 Thanks for responding, once the plugin remove the session still gives me a segmentation fault.
Does the -B option supposed to launch Ardour with all plugins disabled ?

I did not compile anything, just using the current 7.3 deb file with gdb for debbugin (no nightly, not compiled by hand).

[x42 (Robin Gareus)]

@Nomys_Tempar

Does the -B option supposed to launch Ardour with all plugins disabled ?

No, that only bypasses them. Plugins are still instantiated and their state is restored. Many plugins also still run and bypass the signal internally.

You want -d to disable plugins. see Ardour7 --help

  -B, --bypass-plugins        Bypass all plugins in an existing session
  -d, --disable-plugins       Disable all plugins (safe mode)

or use the “safe mode” option in the recent session dialog.

[Nomys_Tempar]

@x42 Still a seg fault with -d option or with safe mode.

I don’t think the plugin is at fault here.
My x42 plugins version is 20220107-1 (I’m on MXLinux21).

[Nomys_Tempar]

I managed to fill a bug report in the bug tracker with a link to download the session file.

[Nomys_Tempar]

Ok so I ran some tests. I deleted all files in my session in:

• analysis folder,
• external folder,
• interchange sub-folders,
• peaks folder,
• plugin folder.
  I ran Ardour each time in safe mode and ignore the missing files to try to have a ‘blank session’.

It didn’t work at all. I keep getting:

@Nomys_Tempar

I don’t think the plugin is at fault here.
My x42 plugins version is 20220107-1 (I’m on MXLinux21).

Just because I don’t think it has been clarified (Didn’t see it when I skimmed through to check), is this the compiled version of Ardour from this site? If not is the behavior the same when running with -D on the compiled version from this site (The free version would tell us if needed)?

  Seablade

[Nomys_Tempar]

It is indeed the compiled version from this site.
I was with 7.2 and tried it with 7.3 with pretty much the same result.

[peder (Peder Hedlund)]

Try mv ~/.config/ardour7 ~/.config/_ardour7 before starting Ardour; in case there’s something weird in your user settings

The next step would be to rename the lv2 plugin folders, to make 100% sure there isn’t a plugin that’s causing the crash
