griddata segmentation fault

Hi there,

The error after I run the griddata is
panic: Segmentation fault -- stopping myself...
attempting to save variables to `octave-core'...
save to `octave-core' complete
Segmentation fault

To reproduce the error, run the following script:
x = rand(1,100);
y = rand(1,100);
z = rand(1,100);
[xx yy] = meshgrid(0.2:0.1:0.8,0.2:0.1:0.8);
zz = griddata(x,y,z,xx,yy);

I am using octave 3.0.3, I have installed qhull package (2003.1), and the above script runs correctly under matlab.
(I have tried to change "tri = delaunay (x, y);" to "tri = delaunay (x, y, "QJ");" in "octave/3.0.3/m/geometry/griddata.m", as mentioned in some posts, but it did not work.)

Any ideas to fix this problem?
