Hello,

Using the Delaunay_triangulation class with Epick_d kernel, we noticed that after streaming the triangulation to a (text) file, closing the file, the loading that file back into a new Delaunay_triangulatin object, the "invalid" property is set to "true".

When trying to call the locate() function on the triangulation initialized from the file, we get "trouble" (error messages). However if we make a copy to a third triangulation object using a copy constructor, then the new triangulation does not have "invalid" set and it works properly.

Is this a known issue ? Or should I report it as a bug with more detail ?

Regards,


Renaud
