The NaNs at the border are due to the fact that for this example only a
random region of interior points are defined. Everything outside that
region is undefined and therefor NaN.
This is a feature of that test and is the correct behavior, so it is
obviously correct now.
A better test would be to use something where you know exactly at which
places NaNs have to appear (use a test without random numbers but
something with constants).
(It was of course the wrong behavior when everything was NaN which I
could also reproduce with qhull6)
