Presently looking at option two for debugging Ardour. Information I’ve found on the location of the core file on ubuntu points to /var/log/aport.log where I’m seeing crash information about the Ardour version I’m currently using. Is this the file expected in bug reports?
No it is not. You will not get core files unless (a) you have your corefile size limit set to some large number (running
ulimit -c unlimited in the terminal window where you start Ardour for debugging purposes is a good idea) and (b) your distribution does not try to interfere with the creation of core files.
