What actually prints “Segmentation fault”?

问题

Which binary or piece of code is printing Segmentation fault on the console when an error occurs?

回答1:

That's the invoking shell's job, when job control is enabled. Demonstration with bash:

$ set +m                    # disable job control
$ bash -c 'kill -SEGV $$'
$ set -m                    # enable job control
$ bash -c 'kill -SEGV $$'
Segmentation fault (core dumped)
