I personally don't know what this file was intended to be used for.
Anyway the outer boundary is not correctly oriented for this
application. If you add:

outer.reverse_orientation();

Then it will work as expected.

Hello!

Does the Create_skeleton_and_offset_polygons_with_holes_2 example run with
sample_4.dat? I tested it now with two different installations (with Windows
and Ubuntu). Can someone test that for me?

The error is:
CGAL error: assertion violation!
EXpression: lParent
File: ... /CGAL/arrange_offset_polygon_2.h
Line: 93

Best regards
