Thanks for your quick reply.

However, this is not intuitive, the compiler should be "free to do anything" in
a sensible intuitive manner.

The for loop is well defined and there is no conceivable circumstance that
should allow it to loop forever.

The optimized/unoptimized code should work the same but it does not.

If you want to make the unoptimized code loop for ever I'll be more than happy

Thanks again.
