Hm, does it work for you when installed via conda?

You are misinterpreting what those methods are for, see the docstring: ``` Returns True if other and this shape are same, i.e. if they share the same TShape with the...

If you are able to load the model back to CQ, you could use bool cut to compare the original and final. There is a `tol` parameter that might be...

Thanks @akaszynski , could you paste what is in your env (e.g. `conda list` or similar)?

I'll plug the free function API here (you'll have to be on master): ```python from cadquery.occ_impl.shapes import * # start with a box b = box(1,1,1) # split int top...

Would you be able to step through the failing test in python share the object (as `brep`) passed to `ShapeUpgrade_UnifySameDomain`?

So the idea was that you debug (in pdb) the first segfaulting test and share the problematic shape as a `brep` file. BTW: how is OCCT compiled? Can you share...

That does not look too weird. I assume that `cq.Workplane("YZ").circle(r_wheel).extrude(w_wheel, both=True, clean=False)` does not segfault, right? Looking at your cmake flags, `-DBUILD_ENABLE_FPE_SIGNAL_HANDLER=no` might be suspicious. I never unset it, could...

OK, could you then check with a debug build of OCCT and share the coredump?

AFAICT `this` is null and that is the direct cause of the behavior. I'm not sure what to make out of this. Two random ideas: (1) does changing of the...
