Ramped tempo going down crashing Ardour?

Hello
I try to use ramped tempo to go from 132 bpm to 140 bpm (that’s ok), then 140 to 70 (that’s sometimes ok) then 70 to 140 (that is never ok)…
The tracks use some plugins (geonkick and ACE fluidsynth, and others) and some automations, so I don’t really know if it comes from ardour or not, but I have a segmentation fault
(OS : Debian 12)

Here the logs (carry return are just after the play):

Segmentation fault

Any idea ?

I’m shooting in the dark here, but are you by any chance using a control surface? If so, can you try to reproduce the problem with the controller disabled or disconnected?

Thanks for for idea : Even if I have no control surface, I tried to check if it changes something when all tracks are disconnected …but no, it doesn’t

Now, I’m gonna check other things, I’ll tell you back.

I tried removing tracks with geonkick (geonkisck single)… that seems that works…

I’m trying to reproduce it, with a solo track of geonkick, it seems that they are others race conditions…

any luck? the only thing I can think of is update distrho and geonkick. the log makes it seem like there’s some sort of issue with a controller. geonkick’s latest version addresses an issue with crashes in reaper. maybe is was causing problems with ardour as well…?

the warnings are not on the geonkick tracks.

I made session with the only the 5 geonkick tracks of the original : it fails

Then I tried a session file track by track (always from the oritignal), it passes each time

But when I have 2 track together in the same session it fails

When i launch ardour --gdb , it tell me:

Thread 75 “RT-main-(nil)” received signal SIGSEGV, Segmentation fault.
[Switching to Thread 0x7fffaee55d40 (LWP 31849)]
0x00007ffff7ac3dab in ARDOUR::ProcessThread::get_route_buffers(ARDOUR::ChanCount, bool) () from /usr/lib/ardour6/libardour.so.3

All those messages are from a plugin that was created with DPF, and judging from the last message, the crash seems to be caused by closing a plugin GUI.

I dimly recall there was a bug related to that which fixed around 10 months ago.

Thanks Robin, but I don’t think it comes from DPF, because here are the logs with only the 5 geonkick tracks, with a session that fails:

Can you reproduce this without using the geonkick plugin?

With all geonkick disabled, ardour doesn’t crash
With ACE reasonable synth instead of each geonkick plugin, ardour doesn’t crash

So I can’t reproduce this without using the geonkick plugin.

So it seems to be a problem with geonkick.

One explanation would be that the plugin does not calculate tempo correctly and produces too much output data (causing a buffer overflow). - but that is mostly speculation, based on the get_route_buffers segfault.

I trust you’re using the latest version of the plugin?

Sorry for the late reply Robin

Yes, geonkick 2.9.1

I don,t know if it can help, but here are some parts of journalctl -t kernel

By the way, I’m using the testing release of Debian (12), and I think it could be a root cause :wink:

So, if no one else in stable release has this crash, I think I’ll do with it

Big thanks to whose who tried to help me, the Ardour community is great!
