This flamewar in the comments is hilarious.

To all concerned, here is a much simpler example.  This does appear to be a
regression.  I apologize that I cannot help fix it, as it's a really useful
feature that helps catch bugs.  Hat's off to you folks working hard on gcc.

int
main(void)
{
        int len, i;

        for(i = 0; i < 5; i++) {
                printf("%d\n", len);            // no warning!
                len = 10;
        }

        return 0;
}
