Comment Comment by sacnoradhq Find me one contemporary example (ANSI C) with a disassembled screenshot.This is writing sizeof(char) (== 1 almost everywhere) zero to address zero. It is not using a NULL macro or other predefined symbol.In the real world, this would generally write a byte to address 0000:0000, leading to UB because it would fuck up the divide-by-zero IV.PS: I used Borland C++ 3.1, Microsoft C++ 3.x and 4.5x, Watcom, and early GNU. parent sacnoradhq 3 years ago
