That's what I thought when I wrote the testcase.  But then it occured to me
that the optimizers could assume that since i is undefined, i /= 0 is
undefined, and hence the compiler could probably validly assume that the
assignment will never be executed.  I don't know if that's what happened.
We'll see once you've run your various testers again.
