Bu it is unspecified! How can you compare the identity of something
that has none? "void" means: the return value is not specific and may
even be different over multiple invocations. It gives the compiler the
opportunity to not worry about returning some particular value, since
it indicates that a computation was performed solely for it's
side effects.

In short: don't rely on the result of "void". It's reason of existence
is to have something to return as a result that should not be
relied on.
