     Type:  Support Requests  |      Status:  new          
Milestone:  To Be Determined  |   Component:  serialization
  Version:  Boost 1.50.0      |    Severity:  Problem      
 Keywords:  warning fix       |  
------------------------------+---------------------------------------------
 warning C4244: 'argument' : conversion from 'std::streamsize' to 'size_t',
 possible loss of data
 compiling this: basic_binary_iprimitive.hpp

 example code:
 namespace boost {
         template <>
         struct hash<ATypeHere>
         {
                 inline size_t operator()(const ATypeHere & obj_p ) const
                 {
                         //  return something
                 }
         };
 }

 If you change size_t to std::streamsize, you will get the exactly same
 warning, but inverted (in a different place)
