What's the shortest code to cause a stack overflow? [closed]

Answer 1

Z-80 assembler -- at memory location 0x0000:

rst 00

one byte -- 0xC7 -- endless loop of pushing the current PC to the stack and jumping to address 0x0000.

Answer 2

Java

Slightly shorter version of the Java solution.

class X{public static void main(String[]a){main(a);}}

Answer 3

Hoot overflow!

//              v___v
let rec f o = f(o);(o)
//             ['---']
//             -"---"-

Answer 4

Every task needs the right tool. Meet the SO Overflow language, optimized to produce stack overflows:

so

Answer 5

3 bytes:

label:
  pusha
  jmp label

Update

According to the (old?) Intel(?) documentation, this is also 3 bytes:

label:
  call label

Answer 6

You could also try this in C#.net

throw new StackOverflowException();
