[Toon-members] GCC bug?

[Ethan Eade]

Using gcc 4.3.1, the following code does not give correct output if 
using  -02 optimization or greater.
Turning down the optimization (or even adding more lines) will make it 
work.  Is this a compiler bug?

#include <TooN/TooN.h>
using namespace TooN;
using namespace std;

int main()
{
   Vector<2> x = (make_Vector, 1,2);
   double w = 1.0;
  
   cerr << (w * x.as_col()) * x.as_row() << endl;
}
