Hello,

Could you please explain what causes the following warning and how to avoid it (boost 1.36, MSVC9.0SP1):

typedef boost::weak_ptr<Task> TaskWeakPtr;
typedef std::vector<TaskWeakPtr> TaskWeakPtrs;

TaskWeakPtrs tasks_;

TaskWeakPtrs::iterator toRemove = std::remove_if(tasks_.begin(), tasks_.end(), !boost::bind(&TaskWeakPtr::lock, _1));

1>        ]

Thank you!
