Summary0011102: vtkDelaunay2D with some pairs of datasets and transforms crashes
DescriptionWith the attached dataset and the transform defined in code below, vtkDelaunay2D crashes. With that dataset and a different transform all is well. With that transform and a different dataset all is well. I'm sure it has something to do with the degeneracy of the dataset, but there should be a check for that and an error thrown rather than a crash.

Additional InformationIt looks like it happens in vtkDelaunay2D::CheckEdge.
