This seems to work for me with the current sources:

  octave:1> n=200; k=8;
  octave:2> x=rand(n,k); y=rand(n,1); parm = rand(k+1,1);
  octave:3> function a = test(b,x1,x2), a=b; end
  octave:4> function w = solve(fcn, q, ...), w = feval(fcn, q, all_va_args); end
  octave:5> solve('test', parm, y, x)

so I think the problem has already been fixed.
