Comment (by viboes):

 Sorry for not updating the ticket. This has been fixed as


 {{{
         void release_shared_waiters(state_data old_state)
         {
             if(old_state.shared_waiting || old_state.exclusive_waiting)
             {
 BOOST_VERIFY(detail::win32::ReleaseSemaphore(semaphores[unlock_sem],old_state.shared_waiting
 + (old_state.exclusive_waiting?1:0),0)!=0);
             }
         }

 ...
                     if(last_reader)
                     {
                         release_waiters(old_state);
                     }
                     else
                     {
                         release_shared_waiters(old_state);
                     }
 }}}

 Please, could you try it?
