The important thing is not whether an invariant or a precondition does not
hold, but rather do you know who is to blame?
If you know that the caller did something wrong, say "documented undefined
behavior" and do whatever you like.
If you can't determine who is responsible for the error, this falls into the
"internal error - we don't know what happened, please save, exit and
reinstall" category.
