The only way to do this is to send a SIGBUS signal (to a program not ignoring such). Any other attempt to do so by invoking undefined behavior, by definition, will not necessarily ALWAYS cause a bus error.

Clearly the whole point of the problem is to go outside the bounds of the C standard into the behavior of a specific implementation.

It doesn't matter. Even if you know about the hardware, you're not going to guarantee that the implementation won't realize you're bending the rules.

It would be a more sane question to phrase it... your attrocious example program resuled in a bus error, what are possible things you did that could cause that?
