Andrey, I am using v.1.1 in code attached in file. It is a test of 2 files.
Please, take a look at those files, tell if you succeed to compile them.
This is the same code as above but without adapter, which worked.

Info:

after tracing I get 

Here is the problem, WatForSingleObject is called and after one BOOST_LOG
macros app. is frozen.

basic_time_mutex.cpp
void lock()
            {
                if(try_lock())
                {
                    return;
                }
                long old_count=active_count;
                mark_waiting_and_try_lock(old_count);

                if(old_count&lock_flag_value)
                {
                    bool lock_acquired=false;
                    void* const sem=get_event();

                    do
                    {
                        BOOST_VERIFY(win32::WaitForSingleObject(
                                        
sem,::boost::detail::win32::infinite)==0);
                        clear_waiting_and_try_lock(old_count);
                        lock_acquired=!(old_count&lock_flag_value);
                    }
                    while(!lock_acquired);
                }
            }

Then function below returns false.

sink_frontends.cpp
template< typename CharT >
BOOST_LOG_EXPORT bool synchronous_frontend< CharT >::try_consume(record_type
const& record)
{
    register implementation* pImpl = this->BOOST_NESTED_TEMPLATE get_impl<
implementation >();
    try
    {
        unique_lock< mutex > lock(pImpl->m_BackendMutex, try_to_lock);
        if (lock.owns_lock())
        {
            (pImpl->m_Consume)(pImpl->m_pBackend.get(), record);
            return true;
        }
        else
            return false; // returns 
    }

in locks.hpp

 bool try_lock()
        {
            if(m==0)
            {
               
boost::throw_exception(boost::lock_error(system::errc::operation_not_permitted,
"boost unique_lock has no mutex"));
            }
            if(owns_lock()) // failed 
is_locked=false;
