Comment (by chris_kohlhoff):

 Your proposed resolution is not valid. As noted on the MSDN page you
 linked to, !GetQueuedCompletionStatus also returns false if it
 successfully dequeues a completion packet but the operation associated
 with that completion packet was itself unsuccessful.

 The real problem is probably that !WriteFile has failed immediately with a
 specific error code (returned by !GetLastError) that still results in a
 completion packet being queued, but asio does not recognise it as such.
 Please let me know the error code associated with the failed !WriteFile
 call.
