Summary	0003961: DogLeg fail
Description	Following the request in the Report View here is a situation where DogLeg fails but LevenbergMarquardt succeeds
Steps To Reproduce	Repeat the steps in the video in the following post with the file m_constrained_2.fsctd from the same post: Post 1.Open sketch01 2.Change dimmension 10mm to 24mm 3.Change dimmension 6mm to 20mm 4.Exit sketch In report view I get: EigenSparseQR, Threads: 1, Vectorization: On, Pivot Threshold: 1e-13, Params: 12, Constr: 12, Rank: 12 Sketcher::setUpSketch()-T:0.081 DL: tolg: 1e-80,
