I call boost::asio::async_write, finally it call "bool
enqueue_operation(Descriptor descriptor, Operation operation)"

In this function , there is code as flow:
while (current_op->next_)
      current_op = current_op->next_;

My process execute it for ever. Using gdb to attach the prcocess, I find :
68          while (current_op->next_)
(gdb) p current_op
$8 = (class boost::asio::detail::reactor_op_queue<int>::op_base *) 0x93381c8
(gdb) p current_op->next_
$9 = (class boost::asio::detail::reactor_op_queue<int>::op_base *) 0x93381c8

current_op and current_op->next_ is the same address.

how did it come true? I have no any clue. Anyone can offer some suggestion?
