11154	Constructing boost::interprocess::interprocess_semaphore throws in MacOS 10.9.5	Jonathan Jones <jonathan.jones@…>	Ion Gaztañaga	"Using boost::interprocess::interprocess_semaphore from Boost 1.56 and running MacOS 10.9.5, it simply throws an exception saying the function is not implemented:

    libc++abi.dylib: terminating with uncaught exception of type boost::interprocess::interprocess_exception: Function not implemented

This is a regression from Boost 1.49 and MacOS 10.9.5, where this works fine.

Looking at the two, it appears that 1.49 is using the generic spin emulation for interprocess_semaphore, whereas 1.56 is implementing interprocess_semaphore using POSIX unnamed semaphores, which aren't implemented in MacOS 10.9.5."
