A few comments and questions...

First the test for degenerate triangles is giving me false positives. The
reason being there are facets that have five points but are rectangular.
Should this be a problem for the AABB tree?

Is there a way to force a polyhedron to be purely triangle, i.e. P.is pure
triangle() will return true?

The polyhedron: poly.off
<http://cgal-discuss.949826.n4.nabble.com/file/n4657729/poly.off>
The point: (1.5, 49, 25)
The backtrace: bt.txt
