From section 3.2.2.2:

"The (nonexistent) value of a *void expression* (an expression
that has type _void_) shall not be used in any way, and implicit
or explicit conversions (except to _void_) shall not be applied
to such an expression."

In other words, yes: there is a specific exception in the
standard that permits this.
