The code in question is:
{{{
383 if (out_type[i] == CELL_TYPE)
384 Rast_get_c_color(&cell[i][cache[point].col],
385 &red, &green, &blue,
&ncolor[i]);
386 else
387 Rast_get_d_color(&dcell[i][cache[point].col],
388 &red, &green, &blue,
&ncolor[i]);
}}}
{{{
> print cache[point].col
$3 = -19297
}}}
The above code needs to check that the indices are within the array's
bounds.
