[Boost-users] [Help] crash in boost::asio::detail::time_queue

Subject: [Boost-users] [Help] crash in boost::asio::detail::time_queue
From: zong jinliang (zongjinliang_at_[hidden])

My code use boost::asio and log4cplus.
There is any memory write error(as follow) which is detected by valgrind.
And i can't fix the question.
I have used log4cplus for a long time, and detect my program in valgrind in
time, havn't found that there is memory error in log4cplus.
This is the first time to use boost::asio.  Anybody meet crash in
boost::asio::detail::time_queue?
