Question: I'm trying to set up the way my server handles core dumps. In order to test it, I'd need a program that always segfaults.

Is there a simple example program that always segfaults?

Answer: 
try this:

```
long* ptr = 0x0; //-- you can also use other random values and likely you will segfault
printf("%f", *ptr);

```
this should die:

```
int main() {
    char *die;
    printf("%d",(int *)die * 200);
    return 0;
}

```

edit:

```
int main() {
    char *die;
    int killer = 200;
    while(1) {
       printf("%d",(int *)die * killer);
       killer = killer * killer;
    }
    return 0;
}

```
