Hi Jurgen,
I recently installed an upgraded version of Layout which uses Python 3.14. My previously working code now fails with a segmentation fault. However the code executes properly when in debug mode with several breakpoints. I am enclosing my discussion of this with Claude.
Following this up - it seems to work if I add a single breakpoint to:
inframe = "/Users/lipton//Dropbox/Consult/Vias/Layout/Sensor_Periph.gds"
and then run the rest of the code in debug mode it executes properly. Sensor_Periph.gds is only 61kb

Interesting! We did not had any problems after the Python upgrade so far. Are you able to share a script code demonstrating this issue? Do you use any further import in Python? The available Python modules have change a bit with the upgrade.
Which LayoutEditor version do you use? The current development version (20260629) of the LayoutEditor has some mayor upgrade in the use of Python, but is still in testing status: https://layouteditor.com/download?release=latest It will allow to use Python in-Process and access the current design instead of the previous external Python.

I am using 20260608. I will try the new version when I get a chance. I see the same error when I comment out the import file commands so I am not sending the gds files.
