10381	Boost log mutex lock failure	anonymous	Andrey Semashev	"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"";
}}}
