Great! If I understand this correctly, the patch will work in all cases
where a noreturn function is called? This would be a great benefit
for Ada, where range checking emits calls in the form

   if (range_check_fails) then
      raise_exception (constraint_error, file, line);
   end if;

I'll try this out ASAP! :-)
