Could you rerun your crashing setup from gdb and provide us with a
backtrace?

In a terminal, go like this:

  $ export GTK_PATH=/usr/lib/ardour2${GTK_PATH:+:$GTK_PATH}
  $ export LD_LIBRARY_PATH=/usr/lib/ardour2${LD_LIBRARY_PATH:+:$LD_LIBRARY_PATH}
  $ gdb /usr/lib/ardour2/ardour-2.8.11
  (gdb) run

When it crashes, say "thread apply all bt", that's the output we need.


If you cannot run ardour from gdb (it might have problems matching the
realtime deadlines), create a core instead:

  $ ulimit -c unlimited
  $ ardour2
  [crash, should give you a file core.something in your CWD]
  $ export GTK_PATH=/usr/lib/ardour2${GTK_PATH:+:$GTK_PATH}
  $ export LD_LIBRARY_PATH=/usr/lib/ardour2${LD_LIBRARY_PATH:+:$LD_LIBRARY_PATH}
  $ gdb --core=XXX
  (gdb) thread apply all bt

If this doesn't work, try the first method but start jackd without
realtime priorities.


TIA
