Yeah - it's complaining about a method in boost::array:

    // Specific for boost::array: simply returns its elems data member.
    template <typename T, std::size_t N>
    T(&get_c_array(boost::array<T,N>& arg))[N]
    {
        return arg.elems;
    }

I don't see any subscript operators there at all. ;-)
I suspect that this is a limitation of the compiler.

Here's a standalone test case:
