OK, another problem in Boost.Fusion:

#include <boost/tr1/tuple.hpp>
#include <boost/tr1/functional.hpp>

int a, b;

std::tr1::tuple<int&, int&> get()
{
   return std::tr1::tuple<int&, int&>(std::tr1::ref(a), std::tr1::ref(b));
}

int main()
{
   std::tr1::tuple<int&, int&> t = get();
   return 0;
}

cannot compile with GCC 4.7.2 / C++11 when defining

The same test case compiles fine without C++11 or without 
BOOST_FUSION_DONT_USE_PREPROCESSED_FILES and in previous versions of 
Boost (1.48 / 1.49)
