Bug description:  do...while(0)

Description:
------------
The while-condition for the example should be 1 and not 0.


Expected result:
----------------
Advanced C users may be familiar with a different usage of the do..while
loop, to allow stopping execution in the middle of code blocks, by
encapsulating them with do..while (1), and using the break  statement. The
following code fragment demonstrates this:

<?php
do {
   if ($i < 5) {
       echo "i is not big enough";
       break;
   }
   $i *= $factor;
   if ($i < $minimum_limit) {
       break;
   }
   echo "i is ok";

   /* process i */

} while (1);
?>
