Your code (with fairly simple modifications) worked fine for me in
VC10 and g++4.X:

#include <boost/static_assert.hpp>

//Added typedef and 'class' keyword below.
typedef int some_type;
template<typename T = some_type, std::size_t N=3> class my_class {
     public:
         my_class(const T& i0) {
              BOOST_STATIC_ASSERT(N==1);
              m_data[0]=i0;
         }
     private:
         T m_data[N];
};

I suspect the error you're seeing might depend on how you instantiate
my_class -- as Steven said, more context is necessary.  If you can
post a compilable example that exhibits the problem our advice will
likely be more helpful.
