  std::cout << "isValid:" << ana.IsValid() << std::endl; // isValid:1
  ShapeUpgrade_UnifySameDomain unify(model);
  unify.Build();
  TopoDS_Shape res = unify.Shape();
}

the model is valid.

When executing Build(), the program got stuck in an infinite loop. The infinite loop occurs in the  RelocatePCurvesToNewUorigin  function.
