#10246: asynchronous_sink sometimes "misses" an attribute
------------------------------+---------------------
 Reporter:  bielecki.b@…      |      Owner:  andysem
     Type:  Bugs              |     Status:  new
Milestone:  To Be Determined  |  Component:  log
  Version:  Boost 1.55.0      |   Severity:  Problem
 Keywords:                    |
------------------------------+---------------------
 Using following
 {{{
 boost::log::sinks::asynchronous_sink<
     boost::log::sinks::text_ostream_backend
 >

 boost::log::sources::severity_channel_logger_mt<Level, Group> scl;
 }}}

 with helper keywords (Level and Group and enums)
 {{{
 namespace {
     BOOST_LOG_ATTRIBUTE_KEYWORD(level, "Severity", Level)
     BOOST_LOG_ATTRIBUTE_KEYWORD(group, "Channel", Group)
 }
 }}}

 configured to use following format
 {{{
 void formatter(
     blog::record_view const& record,
     blog::formatting_ostream& stream
 ) {
     stream << "[" << record[level] << "]";
     stream << "[" << record[group] << "]";
     stream << " " << record[expr::smessage];
 }
 }}}

 In the std::cout and/or in file output one of the attributes (I only
 noticed this happens for level) is (sometimes) missing, even though that
 they are always passed. Example:

 {{{
 BOOST_LOG_CHANNEL_SEV(scl, Group::General, Level::Error) << "Foo";
 }}}

 Possible outputs:[[BR]]
 [Error][General] Foo[[BR]]
 [][General] Foo

 This doesn't happen in case of synchronous sink.
