Well, I figure since Bug #48197 is still open, the issue will be resolved eventually.
If you're facing memory problems because of __get() you might want to sporadically clone the
object: $object = clone $object; The wasted memory is not cloned. Beware that you are trading memory
for runtime. Only consider this if you are facing memory issues or runtime is not an issue.

Just to get this straight. This is not a bug, it's expected behavior.
Anything returned from a magic method is internally handled as a copy. That means that anything a
magic methods returns, even if it's a reference to another object, is kept in memory. That is,
until the $object the magic methods were invoked on, is unset().
Are you kidding me? Not a bug? Where is this not a bug?
A note on this topic wouldn't harm the docs, you know?

A copy of returned variable is done.

What exactly do you mean by "separating return from __get()"? The memory is pumped
regardless of how I return (value, reference). How am I supposed to "separate" here?

There is no memleak, what happens is that the return from __get() needs to be separated.
See bug #48197
