Internal compiler error

[Rich Lee]

Sparc, Solaris 2.6, egcs1.1b

I got Internal compiler error for this little program.

#include <math.h>
#include <vector>
#include <iostream.h>

using std::vector;

template <class X, template<class U> class Container>
X two_norm(const Container<X>& x)
{
  X data = 0;
  for (typename Container<X>::const_iterator i=x.begin(); i!=x.end(); ++i)
    data += *x * *x;

  return sqrt(data);
}

int main()
{
  vector<double> v(100, 1.0);

  cout << two_norm(v) << endl;

  return 0;
}
