Oops, I was distracted by the range-for loop. That error is for the call to
a.resize() which is of course invalid.

But this valid code still gets an ICE from 4.6

#include <vector>

class V : protected std::vector<int>
{
public:
  void echo()
  {
      for (int x:*this) { }
  }
};


int main()
{
    V a;
    a.echo();
}
