You are encouraged to solve this task according to the task description, using any language you may know.
- Task
Create a program that crashes as soon as possible, with as few lines of code as possible. Be smart and don't damage your computer, ok?
- References
ALGOL W
This won't halt the CPU but the program will crash immediately on startup. <lang algolw>assert false.</lang>
6502 Assembly
Upon executing this byte as code, the processor will halt. No interrupts can occur either. This does not occur on 65c02-based hardware such as the Apple II or Atari Lynx. <lang 6502asm> db $02</lang>
8086 Assembly
Disabling interrupts prior to a HLT command will cause the CPU to wait forever.
<lang asm>cli
hlt</lang>
68000 Assembly
The 68000 can only read words or longs at even addresses. Attempting to do so at an odd address will crash the CPU. <lang 68000devpac>CrashBandicoot equ $100001 LEA CrashBandicoot,A0 MOVE.W (A0),D0</lang>
REXX
<lang rexx>=</lang>
Z80 Assembly
The processor is permanently halted. Strangely enough, this does not work on the Game Boy. Rather, both the HALT instruction and the instruction after it are skipped.
<lang z80>di
halt</lang>
