When in a foreach on an array, the next function used on the same array does not return the n+1 element but the n+2 element.

This bug appeared with the 5.2.4 version of PHP and it is still present on 5.6.*

It is absend of version7 and of hhvm

Test script:
---------------
$array = array(array(0,0), array(0,5), array(5,5), array(5,0), array(0,0));

foreach ($array as $point) {
    $next = next($array);
    var_dump($point, $next);
}
