Appears as an issue in mapped_file.hpp if used with std::ios::in.
Issue appears as a copy paste problem from mapped_file_source class.
Issue manifest that const_begin() always return 0 (zero) and const_end()
return 0+size(). To correct the problem const_data() method shall be called
instead of data(). Below is diff with current version:

     iterator end() const { return data() + size(); }

Please enter into bug database (do i need to subscribe to Track to do
it myself?).
Thanks,
