What is the easiest way to make a C++ program crash?

Question

I'm trying to make a Python program that interfaces with a different crashy process (that's out of my hands). Unfortunately the program I'm interfacing with doesn't even crash reliably! So I want to make a quick C++ program that crashes on purpose but I don't actually know the best and shortest way to do that, does anyone know what to put between my: int main() { crashyCodeGoesHere(); } to make my C++ program crash reliably

Answer 1

This code should reliably crash.

#include <iostream>

#define BUFSIZE 10

int main(int argc, const char* argv[]) {

char buf[BUFSIZE];

buf[BUFSIZE + 1] = 'a'; // memory access error here

return 0; // it will never reach this line

}
