reduced form below shows it's a regression since 4.5, only an ICE with C++0x -
appears to be due to C++0x constexpr support

namespace std
{
    template<typename T>
        T min(const T& l, const T& r)
        {
            return l < r ? l : r;
        }
}

using namespace std;

int f();

void g(const int&);

template <typename T>
static
void
call_operator ( )
{
    int const a = f();
    int const b = f();
    int const c = min (a, b);

    g (c - 0);  // ICE
}
