It doesn't report anything in this case since the user account does not
have permission, and I normally disable core dumps (ulimit -c 0):

    Test emacs-tests/seccomp/allows-stdout condition:
    Info: Process output:
          
          Potentially relevant Seccomp audit events:
          Error opening config file (Permission denied)
          NOTE - using built-in logs: /var/log/audit/audit.log
          Error opening /var/log/audit/audit.log (Permission denied)
          
          Potentially useful coredump information:
          [...]
          No coredumps found.
          -- Notice: 1 systemd-coredump@.service unit is running, output
          may be incomplete.

With my root hat on, the audit.log data is attached.

With core dumps enabled:
