-----------------------------------+----------------------------------------
 I have a code snipper using boost::asio library, it runs well complied
 with vs2008, but occurs error compiled with vs2010 beta 2, just like this:
 "Unhandled exception at 0x012ec084 in SimpleC++.exe: 0xC0000005: Access
 violation reading location 0x00000000."

 see code below:

 #include "stdafx.h"
 #include <iostream>
 #include <boost/asio.hpp>
 #include <boost/array.hpp>
 #include <string>

 using namespace std;
 using boost::asio::ip::tcp;

 std::string make_header()
 {
     std::string str ="";
     str += "GET / HTTP/1.1\n";
     str += "Host: www.google.com\n";
     str += "User-Agent: Mozilla/5.0\n";
     str += "Accept: */*\n";
     str += "Accept-Encoding: gzip,deflate\n";
     str += "\n\n";

     return str;
 }

 int main(int argc, char* argv[])
 {
     boost::asio::io_service io_service;
     tcp::resolver resolver(io_service);
     boost::asio::ip::tcp::resolver::query query("www.google.cn", "http");
     tcp::resolver::iterator endpoint_iterator = resolver.resolve(query);
     tcp::resolver::iterator end;

     tcp::socket socket(io_service);
     boost::system::error_code error = boost::asio::error::host_not_found;
     while (error && endpoint_iterator != end)
     {
         socket.close();
          socket.connect(*endpoint_iterator, error);
     }
     if (error)
         throw boost::system::system_error(error);

     std::string message = make_header();

     cout << message << "\n";
     try
     {
         size_t len = socket.send(boost::asio::buffer(message));
         cout << "send: " << len << "\n";
     }
     catch (std::exception e)
     {
         cout << e.what() << std::endl;
     }


     size_t l = 0;
     for (;;)
     {
         boost::array<char, 256> buf;


         size_t len = socket.read_some(boost::asio::buffer(buf), error);
         if (error==boost::asio::error::eof)
             break;
         else if (error)
             throw boost::system::system_error(error);
         l += len;

         std::cout.write(buf.data(), len);

     }
     std::cout <<std::endl << l << " bytes received.\n";

     io_service.run();
     return 0;
 }
