Problem with the file "com.esri.prt.core.dll"

reitsined

Hello,
There is a problem with the file "com.esri.prt.core.dll"
Everything goes well until "export models"
I divided the scene into several parts (6)
Export works very well with 5 of them
As against the sixth named "Paris Est" CityEngine suddenly crashes and closes without finishing the job. A "log" file appears on the desktop. (attached photo)
I of course tried several tries, cut the scene in a different way; nothing to do there is something in this area that causes the crash.
And then CityEngine is struggling to restart.
I wonder what's wrong ...
The latest version of Java is installed and the drivers for the graphics card (Nvidia GTX 960) is current ...
Assistance would be welcome ...
Best regards.

After...
A little research, I realized that this is a group of polygons that problem.
As soon as I change the "rules" of these polygons, export proceeds smoothly
Why these three polygons they refuse to be 'lots'? It crash!
If they are "garden" it works ...
What are they special?
How to prevent against such setbacks? It is not easy to detect what the faulty polygons in large scenes ...
Thank you.
