if either of the sections is omitted the sweep returns a result. |

The test case sweep3.draw seems to be affected by 0025453 it does not longer create a sigsegv but a faulty shape > checkshape Sweep On Shape faulty_1 : BRepCheck_UnorientableShape Shape faulty_2 on shape faulty_1 : BRepCheck_BadOrientationOfSubshape On Shape faulty_3 : BRepCheck_UnorientableShape Shape faulty_4 on shape faulty_3 : BRepCheck_BadOrientationOfSubshape Faulty shapes in variables faulty_1 to faulty_4 But the other two examples (minihyd and from c29262) still create a SIGSEGV |

I got a new user report that generates a similar stacktrace. (DRAWEXE example included in sweep-arc2.zip) |

I got a new user report that generates a similar stacktrace. (DRAWEXE example included in sweep-negpara1.zip) it involves an ellipse with negative parameter range: "mkedge Ellipse-edge Ellipse-curve 3.141592653589793 0" Program received signal SIGSEGV, Segmentation fault.

Problem described in issue is reproduced on current state of OCCT. |

Also we have an exception on following script (trying to sweep line along circle if line starts from circle's center): pload ALL circle c1 0 0 0 40 mkedge e1 c1 wire w1 e1 line l1 0 0 0 0 0 20 mkedge e2 l1 0 10 wire w2 e2 mksweep w1 addsweep w2 buildsweep sw1 |
