[gts-general] gts_surface_intersection memory leak

[Michele C. <mic...@un...>]

Hi everybody,

I am using extensively using boolean operation within my code. In particular, I am at the moment interested in the evaluation of the line of intersection among two objects.

For this, I use  gts_surface_intersection. Unfortunately, I encountered some problem while deallocating memory.

In what follow you may find a simple example code showing the memory leak I have found. Am i doing something wrong? Or if the function gts_surface_intersection creating copies of the original surfaces that I am not deleting?

Thank you in advance

Michele
