placement new issues with gcc6

placement_new_issues_with_gcc6

There seems to be a misunderstanding in the following parts.
src/boost/function/function_template.hpp at line 572
src/boost/function/function_base.hpp at line 308

Here are the errors as reported by gcc:

src/boost/function/function_template.hpp:572:11: error: placement new constructing an object of type 'network_boost::algorithm::detail::token_finderF<network::detail::normalize_path_segments(network::string_view)::<lambda(char)> >' and size '8' in a region of type 'char' and size '1' [-Werror=placement-new=]
src/boost/function/function_base.hpp:308:13: error: placement new constructing an object of type 'network_boost::detail::function::functor_manager_common<network_boost::algorithm::detail::token_finderF<network::detail::normalize_path_segments(network::string_view)::<lambda(char)> > >::functor_type {aka network_boost::algorithm::detail::token_finderF<network::detail::normalize_path_segments(network::string_view)::<lambda(char)> >}' and size '8' in a region of type 'char' and size '1' [-Werror=placement-new=]



It's apparently something boost needs to address. Here's what I did to shut the compiler up.
