A Great Axe familiarity only gives one 3.125% less stamina consumption per swing in case of a fire axe, that is negligibly low anyway.

I don't understand what you're asking me to provide. There're more than two segfaulting tests, as i'm commenting them out. Is your request about `testBrepImportExport`, or about the first crashing...

I failed to export brep, but produced a minimal segfault reproducer: ``` #!/usr/bin/python3 import cadquery as cq r_wheel = 25 w_wheel = 10 wheel = cq.Workplane("YZ").circle(r_wheel).extrude(w_wheel, both=True) wheel.val().exportBrep("wheel.brep") ```
