Comment:

 It is weird. I develop Boost.Thread using OSX El Capitan 10.11.4 and I
 never had any similar issue.

 Thanks for the information about when this was working and when not.

 Oh, I see it now

 the code is

 {{{
 #if defined BOOST_THREAD_HAS_CONDATTR_SET_CLOCK_MONOTONIC

     inline timespec timespec_now_monotonic()
     {
       timespec ts;

       if ( ::clock_gettime( CLOCK_MONOTONIC, &ts ) )
       {
         ts.tv_sec = 0;
         ts.tv_nsec = 0;
         BOOST_ASSERT(0 && "Boost::Thread - Internal Error");
       }
       return ts;
     }
 #endif
 }}}

 This was a failed trial to use condition variables with monotonic clocks.
 BTW, Mac Os doesn't provide condition variables with monotonic clocks

 Are you defining BOOST_THREAD_HAS_CONDATTR_SET_CLOCK_MONOTONIC?
 If yes, please don't do it :)

 The code should work as before introducing this regression.

 We are working on this, see https://github.com/boostorg/thread/pull/142.
 Hopping we will have this ready for boost-1.66.
