[boost] [asio] static data member as buffer arg

Any obvious reason that supplying a static const data member to a buffer, 
for example:

class Client
{
   static const unsigned int sHandShakeGreeting = 0x01020304;

   ba::stream_socket mSock;

   ...

   void SomeFnc()
   {
      ba::async_write( aSocket
                     , ba::buffer(&sHandShakeGreeting,4)
                     , boost::bind( &Client::OnSent, this, _1, _2 ) );
   }

   ...
};

would behave differently from:

const unsigned int sHandShakeGreeting = 0x01020304;

class Client
{

   ba::stream_socket mSock;

   ...

   void SomeFnc()
   {
      ba::async_write( aSocket
                     , ba::buffer(&sHandShakeGreeting,4)
                     , boost::bind( &Client::OnSent, this, _1, _2 ) );
   }

   ...
};

The above all occur within a .cpp file. In the latter case the dialog 
continues as expected, but the former results in the server(I don't have 
code for) not receiving a valid value. This is using VC7.1.

Thanks, Jeff
