Why can't I cause a seg fault?

Question

OK for whatever reason I\'m having trouble causing a seg fault. I want to produce one so that I can use gdb to see how to debug one. I have tried both examples

Answer 1

int *hello = NULL;
printf(*hello);

or you can define a struct (say HelloWorld struct)

HelloWorld *myWorld = NULL;
myWorld->world = "hello";

Answer 2

Lots of ways to generate a segfault.

Like dereferencing a bad pointer:

char *s = (char *)0xDEADBEEF;
*s = 'a';

Answer 3

My one line flavor:

*(char *)0 = 0;

Answer 4

If you try to concatenate two constants... you'll get one... at least is a simple way...

strcat("a", "b");
