Thanks for your fast answer! :). I set
std::setprecision(17) with the same results. Have you execute the demo with Windows? In my case I executed the program in Windows 10.

No idea what you did, if I open the polyhedron demo, load your model
call orient polygon soup and remove self intersections, everything is done in less than a minute on my computer and the output model does not
contain any self-intersection.
Do you have intermediate writing to "string" with a rounding of the coordinates of the point not using the max precision (std::setprecision(17) for the ostream)?

This is may application that i compile in windows in Release with the showed
CMakeList.txt and cgal_vtk_test.cpp files. When I try to repair this file:
Number intersection: 290
https://drive.google.com/file/d/1uqcbZqgtbiiXYjKnzzb5d-OXm4JAHqdx/view?usp=sharing
1. my application build in Release generate the following file:
Number intersections: 179
Add some visible holes and some deformations.
Repairing time:..................201.128 seconds.
https://drive.google.com/file/d/13Vfw0pP5Ymw0oo4RnfRjKTI_aTndb6P4/view?usp=sharing
2. my application compiled in Debug, it generate the following file:
Number intersections: 4
Repairing time:..................1072.96 seconds.
https://drive.google.com/file/d/1x1Z7qaNcnfGC8a24qzJI-DZEF3qqeLqq/view?usp=sharing
with warnings:
_expression_ : !"Returning no output. Filling hole with extra triangles is not
successful!"
File :
C:\dev\CGAL-4.12\include\CGAL/Polygon_mesh_processing/internal/Hole_filling/Triangulate_hole_polyline.h
Line : 1103
Explanation:
Refer to the bug-reporting instructions at
https://www.cgal.org/bug_report.html
The problem is that in debug build it takes around 17 min for reparacion and
in Release it only takes 3 minutes, but in relese build it modify the
original mesh and add a big hole(pleas check links to files)
What's wrong?
