Bug#935980: jackd2: Segfaults when qjackctl patchbay is activated

[Bernhard Übelacker]

Hello Chris,
I added it to your report guessing that it might be the issue
you observed. Now I see your setup is way more complex than my test.

To reveal some more information about your issue, you could install
the package systemd-coredump, then in the journal should a
backtrace appear after a crash. Additional a coredump should be
collected for later investigation (coredumpctl list).
More details might be available in the journal if dbgsym packages
for related binaries are installed (more details in [1]).

If additionally gdb is installed a coredump could be inspected
by 'coredumpctl gdb [PID]'.

Kind regards,
Bernhard
