From Jargon File (4.2.0, 31 JAN 2000) [jargon]:
DEADBEEF /ded-beef/ n.   The hexadecimal word-fill pattern for    freshly allocated memory (decimal -21524111) 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 {heisenbug}s into {Bohr bug}s.   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}.
From The Free On-line Dictionary of Computing (15Feb98) [foldoc]:
DEADBEEF          /ded-beef/ The {hexadecimal} pattern       used to fill words of freshly allocated memory under a number       of {IBM} environments including the {RS/6000}; equal to       decimal 3,735,928,559 (unsigned) or -559,038,737 (32-bit       signed).   As in "Your program is DEADBEEF" (meaning gone,       aborted, flushed from memory).          (1998-06-29)
