vector `v` on the stack does not agree with the corresponding part on the
heap. `v` still thinks there are three elements in the vector and will
happily let us access the non existent element `v[2]` but as you might
already know this is a recipe for disaster. Especially because it might lead
to a segmentation fault or worse allow an unauthorized user to read from
memory to which they don't have access.
