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:

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.
