Thanks for the report. It seems that Mac Os incorrectly reports POSIX semaphores as supported, this was fixed in master and develop branches, can you try Boost 1.58 Beta to confirm this was fixed for you?

Thanks for responding so quickly!

Would it be possible for you to attach a patch to this bug report that we can apply to 1.56.0?

There were too many changes for a clean patch. For a workaround change:

boost/interprocess/sync/interprocess_semaphore.hpp

and change the preprocessor code to avoid entering in the following configuration

#if !defined(BOOST_INTERPROCESS_FORCE_GENERIC_EMULATION) && \
   (defined(BOOST_INTERPROCESS_POSIX_PROCESS_SHARED) && defined(BOOST_INTERPROCESS_POSIX_NAMED_SEMAPHORES))
   #include <boost/interprocess/sync/posix/semaphore.hpp>
   #define BOOST_INTERPROCESS_USE_POSIX

It should use configuration:

#elif !defined(BOOST_INTERPROCESS_DOXYGEN_INVOKED)
   #include <boost/interprocess/sync/spin/semaphore.hpp>
   #define BOOST_INTERPROCESS_USE_GENERIC_EMULATION
#endif

Confirmed (finally) that this was fixed in Boost 1.65.1. May have been fixed in earlier releases, since we jumped from 1.56.0 directly to 1.65.1.
