|

a number of IBM environments, including the RS/6000. Some modern debugging

tools deliberately fill freed memory with this value as a way of converting

As in “<span class="quote">Your program is DEADBEEF</span>” (meaning gone, aborted,
|

flushed from memory); if you start from an odd half-word boundary, of
|

course, you have BEEFDEAD. See also the anecdote under
