Your data set has a sharp edge. The Surface Mesh Generator of CGAL do not
handle sharp edges properly.

Losen the third parameter of your CGAL::Surface_mesh_default_criteria_3<Tr>
object, so that the sharp edge is approximated with bigger triangles.

Thanks for explanation.
But why it works most of the time and fails at other time ?
Is this related to random number generator's seed ? (http://bit.ly/dJZL6K)
It should not. The one of the example should be correct.

Is it possible to change the kernel it's using to something else or I have to write my own '

Surface_mesh_triangulation_3' ?
