Your expectation is wrong.

The functions that produce a different values from what you expect are binding
a reference of some type X to an object that is not reference-compatible with
X, which requires the creation of a temporary of type X. The temporary has a
different address from the original object.

Any conforming C++ compiler will produce similar results.
