Thanks.

That alas is not possible because it isn't a problem unless there is a bug in
the cmmpiler, and right now there doesn't seem to be one that relates to this.
If anything, this will cause a problem if we mess up code somewhere, so it is
meant as a safeguard against potentiallu using a valued that is no longer
valid.
So, no test is possible.
