DEADBEEF
 /ded?beef/, n.

    The hexadecimal word-fill pattern for freshly allocated memory under 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
    heisenbugs into Bohr bugs. As in ?Your program is DEADBEEF? (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 fool
    and dead beef attack.
