--- Comment #2 from Jürgen Reuter <juergen.reuter at desy dot de> --- I see this problem both on MAC OS X 10.13.1 with r254916 (and the patch mentioned) as well as on Ubuntu 14.04.5 LTS with r255190. r253161 still worked fine. We see this kind of behaviour in two different bind(C) interfaces to external C++ libraries.
