Summary0029824: Intersection of cylinder and sphere is incorrect
DescriptionThis problem can be solved by modifying IntPatch_ALineToWLine: method MakeWLine sometimes generates two different points with the same parameter on "ALine" - a vertex and an ordinary point. But when preventing the excess ordinary point from addition to the "WLine", we have a regression: different structures of the pcurve in the case "bugs modalg_6 bug27431" on Linux and Windows platforms.
Steps To Reproducerestore [locate_data_file OCC20964_revsolid.brep] b1
