Upstream bug report filed.
https://gitlab.com/mbunkus/mkvtoolnix/issues/2599 is the one? The minor API change is linked in comment 0 (first line). Other Boost.Algorithm consumers (some of which use boost::split) built fine.
(In reply to Jan Beich from comment #2) Yes, that's the one. I am doing the test build right now, should be finished in a couple of minutes.
