Summary0033561: BRepAlgoAPI_Defeaturing never finishes
DescriptionWhen use BRepAlgoAPI_Defeaturing to remove a small face (created by BRepFilletAPI_MakeFillet) (the brep file is attahced), the BRepAlgoAPI_Defeaturing never finishes, it loops in IntTools_BeanFaceIntersector::ComputeLocalized with huge amount of surface ranges (20355, 40000+, ...), tested with 7.6.1, 7.7.0, 7.8.0
Steps To ReproduceRun below test code with attached brep file:

void test()
{
    BRep_Builder bb;
    TopoDS_Shape targetEntityShape;
    const char* brepFile = "D:/tmp/anc101_def.brep";

    if (!BRepTools::Read(targetEntityShape, brepFile, bb)) {
        return;
    }

    bool isValid = BRepCheck_Analyzer(targetEntityShape).IsValid();
    if (!isValid) {
        return;
    }

    TopoDS_Face face;
    int i = 0;
    for (TopExp_Explorer faceExplorer(targetEntityShape, TopAbs_FACE); faceExplorer.More(); faceExplorer.Next()) {
        if (i == 1) {
            face = TopoDS::Face(faceExplorer.Current());
            break;
        }
        i++;
    }

    TopTools_ListOfShape faceShapes;
    faceShapes.Append(face);

    BRepAlgoAPI_Defeaturing aDefeaturing;

    aDefeaturing.SetShape(targetEntityShape);
    aDefeaturing.AddFacesToRemove(faceShapes);
    aDefeaturing.SetRunParallel(false);
    aDefeaturing.SetToFillHistory(true);
    // Perform.
    aDefeaturing.Build();

    if (!aDefeaturing.IsDone() || aDefeaturing.HasWarnings()) {
        return;
    }

    TopoDS_Shape result = aDefeaturing.Shape();
    return;
}
