 Nothing, of course. I may have identified a similar issue in KF5 code
 however, and might file a bug report for that.

 Has this been tried? Has anyone tried using a MacPorts clang compiler?
 (`configure.compiler=macports-clang-N` where N is 5.0 or higher)?

 If all else fails I could talk willing volunteers through installing my
 version of the GCC 7.3 compiler that has a `-stdlib=libc++` option.
