But 'octave --no-gui' is not the same thing as 'octave-cli'. I would
like to see the backtrace with this crash occurring in 'octave-cli'.

This backtrace:

is not very helpful because it only shows a jack thread running, there
is nothing there about what Octave is doing.

Please try with 'octave-cli', with octave dbgsym packages installed as
well, and use 'thread apply all bt' in gdb to be sure to capture all
running threads.
