But a compiler is not required to take action to make 'i' undefined.
Undefined is just that: the standard does not predict the value present
in 'i' after termination of the loop.  It may be the value before start
of the loop; the last value assigned; the same plus 1; NaN; 24723;
or whatever you fancy.
