DescriptionForum discussion:
  https://forum.freecadweb.org/viewtopic.php?f=3&t=56029&sid=cae9731349d24c2a6929a890bf2208b6
Steps To Reproduce- load the file Bug_Sketcher_NotRedundant_2_5_simplified.FCStd
- edit sketch Sk_Diamond
- set length of Edge2 to 0.4mm
-> The diamond shape collapses on itself, the top two legs folding down onto the bottom
   This is a violation of the L2_nrm_L3 constraint
-> solver reports 1 DOF
-> Report View shows
  Updating geometry: Error build geometry(2): Both points are equal
  Invalid solution from SQP(augmented system) solver
- close sketcher
-> an error is reported for the sketch.
