Template template parameters don't work

Question

Consider the following code:
#include <iostream>
#include <algorithm>
template <template <typename T, int I> class Container, typename type, int size>
struct ContainerTraits
     typedef typename Container<type, size>::type value_type;
template <typename T, int N>
class MyContainer
     public:
          typedef T type;
          static const int SIZE = N;
          T* begin() { return data; }
          T* end() { return data+N; }
          T &operator[](int index) { return data[index]; }
     private:
          T data[N];
template <template <typename T, int I> class Container, typename type, int size>
void fillZeroContainer(Container<type, size> c)
     typedef ContainerTraits<Container, type, size> CTraits;
     typedef typename CTraits::value_type value_type;
     std::fill(c.begin(), c.end(), value_type(0));
int main()
     MyContainer<float, 4> c;
     fillZeroContainer(c);
     std::cout << c[0] << std::endl;
     // Once the rest of the code compiles, try to uncomment this.
//      float array[int(c[0]) + 2];
//      array[0] = 0;
     return 0;
Compiling yields:

$ sunCC sunCCproblem.cc

This is Sun Studio 12 (x86) on Linux AMD64 (ubuntu).
I think it is a bug in the compiler. GCC and Intel have no problem compiling this code.
If that is not correct, please let me know what shold be corrected to make the code compile.
Thanks in advance,
