Re: [Boost-users] [fusion] Weird compiler error

When adding ::value to is_same<...> it works. Thanks Shunsuke for the tip.

#include <boost/fusion/sequence.hpp>

using namespace std;
using namespace boost;

int _tmain(int argc, _TCHAR* argv[])
{
   typedef fusion::map< fusion::pair<int, char>, fusion::pair<char,
char>, fusion::pair<double, char> > mymap;
   BOOST_STATIC_ASSERT((boost::is_same<
fusion::result_of::at_key<mymap, int>::type, char&>::value));

   return 0;
}

I have downloaded the CVS Head but here I'm getting an Internal
Compiler Error. Is that a known issue?
