I don't think so... this looks very similar to the code that the
TestBuilder uses to run the ConformingDelaunayTriangulationBuilder. The
CDTB extracts all line segments from whatever geometry is provided as the
constraints.
Try running your example in the TestBuilder and see if it works. Then
perhaps debug into both and see where they diverge.
