Details:

Some testing functions in on octave-forge/main/optim are failing with a
segmentation fault. I tried to identify the the problem and could reduce the
problem to the following test case. 

  clear 
  clear functions 

  function v = ff(x,y,t)
    v = x'*y;
  endfunction

  aa{1}=[1;2];
  aa{2}=[2;3];
  aa{3}=1;
  f = 'ff'; 

  feval (f, aa{1}, aa{2}, aa{3})        # is fine 

  feval (f, aa{:})        # segmentation fault, 


The last command "feval(f,aa{:})" causes a segmentation fault, while the
previous one works fine.
