Saying code like that "depend[s] on undefined behavior" is too kind. Anyone who writes code that assumes the location of a variable based on the location of another variable is bat-!*()% crazystupid.

It could be an exercise on exploring the details of how the compiler works, and a decent explanation on why undefined behavior is undefined; you ask for a variable and you get a variable, it's wholly up to the compiler what goes where.

The danger is that they will see this, decide "oh, that's how it works" and rely on this undefined behavior, when in reality they are depending on something that can be different everywhere.
