 Yes, it is `rapidjson` is broken. I have seen a number of examples of the
 same failure. Just now:

 It is fixed in `rapidjson-devel`. However it is not obvious for anyone
 just trying to build some port which relies on `rapidjson` that instead
 `rapidjson-devel` must be used. The port should be updated or at least a
 fix for this backported.
