Hello,

I have a class called ByteSink that has a move constructor and move assignment operator. I pass an object of type ByteSink into bood::bind() by-value and it fails to compile. First, here is my call to boost::bind():

void SerialClient::Write( ByteSink data )

{

  m_service.post( boost::bind( &SerialClient::DoWrite, this, data ) );

}

The error message I'm getting will be located at the very bottom of this message to prevent clutter. Note that I am compiling on MSVC9 under Windows. Below is what my move constructor/assignment function prototypes look like for ByteSink:

  /// Uses move semantics.

  ByteSink( ByteSink& other );

  /// Uses move semantics.

  ByteSink& operator= ( ByteSink& other );

And the compiler error I'm getting (It's a bit lengthy) is below. Any idea what is causing this? My best guess is that boost::bind() is using const somewhere, and it cannot find a copy constructor that takes a const ByteSink as a parameter, since I'm not using a typical copy constructor.
