After some work I have found a better example of the bug I am chasing in
getting the circumcenters of the segment delaunay (I attach another sample
program):

main.cpp <http://cgal-discuss.949826.n4.nabble.com/file/n4657350/main.cpp>

I have tried a number of different kernels and number types, all of them
seem to fail (see sample code). In the output text result of running the
included program one can see that the centre for "circle 14" is: (
1.61455e+17, 11.9295 ).

I attach snapshots of the program I am using to draw the results, obviously
the program is just to large to include here, but the data is the same. It
only draws the interior part of the segment voronoi (the medial axis), but
the error is clearly visible in the largely off position of one of the
circumcenters.

Do you have any suggestions that may work (any kernels, traits, number
types...)?
Thank you for your time!

Best,
Pablo.
