These segmentation faults always happen when linuxsampler is involved :(
I'll try to set up a proper backtrace / dump reporting.

The current trace indicates that it's linuxsampler which crashes.

So a a gdb backtrace with debug-version of Linuxsampler and Ardour would be nice to have.

I have been trying already following advice on the IRC - but if I launch linuxsampler from gdb - ardour is trying to open its own instance and gets stuck :(

Crash-Core-Dump (50,037 bytes)
below is the core dump + all messages from the moment I have installed the dbg version.

I have then 
- Loaded up my existing session  (handful of uadio track, one midi track with no plugin initially loaded)
- Loaded up Carla pathcbay to my midi track
- Loaded up Linuxsampler in CArla - connected audio and midi
- Loaded up Salamander PIano in Qsampler
No sound on the midi track :(
So I:
- Created a new midi track
- Copy pasted a few regions from the existing midi track
- Loaded up LInux sampler lv2 directly into this new track
- Loaded up salaamnder piano onto this new channel (that had appeared in Qsampler as expected
- Play  : yes!  sound on the new midi track (linux sampler LV2 direct), no sound on the other one (LInuxampler VIA Carla)
but after a few seconds :  loud buzzy tone  then crash :(((

Dear Developers - I have eventually sorted out a complete backtrace (dbg version) so the attachment should be now helpful - I hope.

Lots of similarities with http://tracker.ardour.org/view.php?id=4462 and http://tracker.ardour.org/view.php?id=4375

sadly not useful. those "in ?? ()" are not meaningful.

for future reference: launch "Ardour5 --gdb" and run ardour inside gdb to produce a proper backtrace.


Anyway, the following already shows it's a bug in linuxsampler, not Ardour:


*** Error in `/opt/Ardour-5.8.263-dbg/bin/ardour-5.8.263': double free or corruption (fasttop): 0x00007f46500588b0 ***

Thanks x42. Sorry for filling up space with irrelevant stuff. I'll try to report to linuxsampler too - and try to get a proper backtrace next time.
Also, even if the bugs originate in LinuxSampler - wouldn't it be desired for Ardour not to crash because of it ?

No it wouldn't. Crash protection is expensive and does not scale. Also session-state may be invalid because a crashed plugin can no longer be asked to save its state.

And most importantly: When a plugin crashes you'll get a dropout or audible click so all hope is lost anyway.
