Недавно наткнулся в коде на код ошибки DEADBEEF и решил поподробнее раскопать тему, оказалось весьма забавно

0xABADBABE ("a bad babe") is used by Apple as the "Boot Zero Block" magic number.
0xBAADF00D ("bad food") is used by Microsoft's LocalAlloc(LMEM_FIXED) to indicate uninitialised allocated heap memory.
0xBADDCAFE ("bad cafe") is used by 'watchmalloc' in OpenSolaris to mark allocated but uninitialized memory.
0xCAFEBABE ("cafe babe") is used by both Mach-O ("Fat binary" in both 68k and PowerPC) to identify object files and the Java programming language to identify Java bytecode class files
0xDEADBEEF ("dead beef") is used by IBM RS/6000 systems, Mac OS on 32-bit PowerPC processors and the Commodore Amiga as a magic debug value. On Sun Microsystems' Solaris, marks freed kernel memory. On OpenVMS, running on Alpha processes DEAD_BEEF can be seen by pressing CTRL-T.
0xDEFEC8ED ("defecated") is the magic number for OpenSolaris core dumps.
0xFEE1DEAD ("feel dead") is used as magic number in Linux reboot system call.
0xFEEDFACE ("feed face") is used as a header for Mach-O binaries, and as an invalid pointer value for 'watchmalloc' in OpenSolaris.
