Most compilers are smart enough to optimize the code in loops and execute only once the computations that have a constant result for each loop. This constant result here seems to be output for 0 iteration, which is an undefined value as good as any other. Once it is stated in documentation that the result is undefined, developpers are free to optimize the code the way they want and ignore the result for 0 iteration.
