If you just have:

#include <boost/variant.hpp>
#include <string>

boost::variant<__int128, char, std::string> v;
v = 56;

This produces an error:

..\..\../boost/variant/variant.hpp:1578:38: error: call of overloaded 
'initialize(void*, boost::move_detail::remove_reference<int&>::type)' is 
ambiguous
