It seems something wrong with GeometrySpiral::ComputeVars when both curvEnd and curvStart are negative and curvEnd greater than curvStart

In this case, with given s, GetGeometryCoords(s, x, y, hdg) would get wrong (x, y, hdg).

Thank you for the report. Can you provide a sample including expected and actual values? Maybe a file which makes the issue obvious?

There is a sample. geometry hdg="2.734621064075011" length="7.532431203846809" s="6.018873210374361" x="161.18988482560962" y="43.5498200468719", spiral curvEnd="0.017152606609492665" curvStart="0.16627793039047342". Something seems wrong with uploading.
