Thanks for the update! This seems to be directly related to a recent, serious bug in the libboost1.54-dev package [1]. Andreas, how can I tag the fact that Orthanc is blocked by this bug with the Debian QA tools? [1] https://bugs.debian.org/cgi-bin/bugreport.cgi?bug=739904
OK, I have just figured out how to mark that a package is affected by a bug.
