Here is a shorter testcase
(reproduced on i686-pc-linux-gnu with gcc version 3.5.0 20040908 (experimental)):

===begin===

double sqrt(double);

template <typename T> class arr
  {
  private:
    long s;
    T *d;

  public:
    arr() : s(0), d(0) {}
    ~arr() { delete[] d; }

    void alloc (long sz);
    const T &operator[] (long n) const {return d[n];}
  };

void blah ()
  {
  arr<int> index;
  index.alloc(10);
  for (int i=0; i<10; ++i)
    {
    int l = int(sqrt(index[0]));
    if (l<0) throw 2;
    }
  }

===end===
