can a sweep be used to create 1-fold tori (using a closed wire as path)
Description
A user reported that he got a problem creating a 1-fold tori.
The result is reported to have self intersections and C0 geometry.
The input wire is not periodic, but it has the same tangency at the start and end.

Participants are labeled by their role within this record.
Another hypothesis would be, that the result is valid and the bopcheck is wrong.
Problem described in issue is reproduced on current state of OCCT.
