What about the one which always crashes?

The following program contains 25 characters, uses no library
functions and segfaults when run:

main(){((void(*)())0)();}

I used the following line to test the code (may save you some typing):

$ echo 'main(){((void(*)())0)();}' > f.c; gcc -o f f.c; ./f; rm f.c f
Segmentation fault
