Unrelated to your patch, but while I'm noticing it, I should mention
that this final step is a bug. abort is required to cause abnormal
program termination. That can be achieved by raise(SIGKILL).

Note that in order for that to work correctly, the bug I just reported
in raise (#15368) needs to be fixed.
