5380,Windows has triggered a breakpoint in my code,greatstar00@…,chris_kohlhoff,"this is the code i used to test (from your website's examples)
'''http://www.boost.org/doc/libs/1_46_0/doc/html/boost_asio/example/echo/async_tcp_echo_server.cpp'''


When i used ""step into"" to debug, i got the following error message:
'''HEAP[test.exe]: HEAP: Free Heap block c46ce8 modified at c46de0 after it was freed
Windows has triggered a breakpoint in test.exe.

This may be due to a corruption of the heap, which indicates a bug in test.exe or any of the DLLs it has loaded.

This may also be due to the user pressing F12 while test.exe has focus.

The output window may have more diagnostic information.

''This is the file it stopped:''
'''\boost\asio\detail\impl\win_iocp_socket_service_base.ipp'''
''line stopped: 334''



''line 334 is in  function: ''
'''void win_iocp_socket_service_base::start_receive_op(
    win_iocp_socket_service_base::base_implementation_type& impl,
    WSABUF* buffers, std::size_t buffer_count,
    socket_base::message_flags flags, bool noop, operation* op)'''


''This is line 334:''
'''int result = ::WSARecv(impl.socket_, buffers,
        static_cast<DWORD>(buffer_count),
        &bytes_transferred, &recv_flags, op, 0);'''



This problem occurs while i send a simple message to the test server, 128 bytes in each request.
