Re: [Boost-users] How to use lock_guard

You should not manually call destructors of automatic (stack allocated) objects. It's an Undefined Behavior and in practice it usually causes destructor to be called twice. You might want to put lock_guard in additional scope.

{ boost::lock_guard<boost::mutex> lock(_mut); // Data received from RS232 _device.GetData(_buffer); // .... CODE .... } // Destructor of lock is called here. signal_OnData(); }

Thanks for the suggestion Roman! Daniele.
