Same thing. Just that you start Ardour instead of LinuxSampler in the way
described. However since LinuxSampler is then launched by Ardour as plugin,
you must install LinuxSampler before launching Ardour. Compiling Ardour with
debugging symbols turned on as well, is definitely recommended.
Another option (instead of starting Ardour with gdb) is enabling coredump
output on your system:
ulimit -c unlimited
Then you can run Ardour normally (without debugger). Once it crashes it will
automatically write a core dump file to the local directory, which is
essentially a memory dump of the Ardour process at the time when the crashed
happened. You can then get the back trace like this:
gdb /full/path/to/ardourbinary /full/path/to/coredumpfile
bt
Both solutions usually yield the same result.
