Hi Gaetan,


Thanks for looking at the build on opensolaris.

 From the test output (below),
it looks like we are dealing with a numerical precision problem.
It may be just a matter of relaxing the tolerance used for comparing
the positions of points.

Currently we are using:

    if( min_dist < result_dist )

maybe we should drop a bit of tolerance like:

    if( min_dist +  vnl_math::eps  < result_dist )


I'm not sure we want to do this today,
just before the release...


     Luis
