DEADBEEF /ded-beef/ n.
(From the Jargon file)
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.
简单的说,deadbeaf就是指引用已经被free的内存,如果在调试器看到这个词,一定得小心啊
