Hi ,

While using Boost (ver 1.51.0) file "addressof.hpp" I am getting following
errors:

*Boost/1.51/Inc/boost/utility/addressof.hpp:41:69: error: cast from 'char*'
to 'std::vector<std::pair<std::basic_string<char>, std::basic_string<char>
> >*' increases required alignment of target type [-Werror=cast-align]
cc1plus: all warnings being treated as errors*

I need to use "Werror" flag in my application.

Any solution for this problem?

*It works fine if i use . Is it the correct solution?*
