Really, I do not understand your argument.
If the argument of New_Line is 0, the procedure is not even called, so its body is irrelevant. The evaluation of the argument raises Constraint_Error as defined in the RM. How could it reboot the computer? The consequences of CE are well-defined.
So what? I think I'm not the only one who is often lost in following your arguments.

What? You surely have read 1.1.5(5)?
