Summary0008471: Crash on loading session (Thread 29 "audioengine" received signal SIGABRT)
DescriptionI've created a session on one machine running Manjaro (desktop PC). Then I've copied it to another machine also running Manjaro (laptop).

One the desktop it works fine - on the laptop it crashes Ardour every time I try to load it.

I've tried the newest nightly build 6.3.333 in debug and produced a complete backtrace.

I've tested this loading he project in "safe mode" - no difference.

I'm attaching two backtraces from two versions of Ardour.
Additional InformationIf you need a test project, please contact me in person.

Correction: this happens on loading or creating *any* session. The problem didn't occur before I've updated the system (pacman -Syu), I'll reboot and see if that changes anything.

Allright, rebooting the system fixed the problem.
I wonder if something could be done to communicate such situations to the user and instruct them what to do.
I suspect maybe some libraries on disk were in different versions than in memory?
