#10381: Boost log mutex lock failure

-----------------------+------------------------------
 I'm using add_console_log(), passing it std::clog. When I build in release
 with optimizations, everything works fine. When building in debug without
 optimizations though, when my program exits there's a core dump as a
 result of the assertion on destruction of the mutex lock failing
 (pthread_mutex_destroy() is returning 16, which iic is EBUSY). I started
 digging through add_console_log(), and if I switch to an asynchronous sink
 there's no issues (I suppose it doesn't need the mutex lock anymore and
 that's why) My compiler's 4.8.3 on FC 20. I've tried with 1.55 and 1.56.

 The code that results in the core dump:
 {{{
 typedef boost::log::sources::severity_logger<severity_level> lgr_type;
 BOOST_LOG_GLOBAL_LOGGER(logger, lgr_type);
 ...
 BOOST_LOG_GLOBAL_LOGGER_INIT(logger, src::severity_logger_mt)
 {
   // setup the console sink
   typedef
 boost::log::sinks::synchronous_sink<boost::log::sinks::text_ostream_backend>
 text_sink;
   boost::shared_ptr<text_sink> consoleSink =
 boost::log::add_console_log(std::clog;

   lgr_type lgr;
   return lgr;
 }
 ...
 BOOST_LOG_SEV(logger::get(), SEV_LVL_TRACE) << "a message";
 }}}
