Segmentation fault while extruding mapped sketch

[kalbfuss]

Freecad produces a segmentation fault, when I attempt to extrude the "Sketch_on_Surface" in the file enclosed with "Fill Extrusion" and "Fill Faces" enabled. Filling faces without extrusion works fine.

The error occurs with the Ubuntu Freecad v1.0 snap and the latest freecad-daily from 26-Dec-2026.

This is is the error message I receive on the command line:
