Minimal C/C++ program that segfaults? [duplicate]
main() { *(int *)0xdeadbeef = 37; } should do it.
main;
Is portable, and segfault in 5chars.
It's a variable declaration - int type is implied (feature copied from B language) and 0 is default value. When executed this tries to execute a number (numbers aren't executable), and causes SIGSEGV.

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