TopoGeo_AddPoint crash on infinite point

[robe]

This one is harder to replicate, cause it only seems to happen with the test topology that the garden tests generated

SELECT TopoGeo_AddPoint('test', '0101000020E6100000000000000000F07F000000000000F07F'::geometry, 20.1)

okay GHA is not complaining about this, so might be a windows only issue or maybe the ordering of the data in windows is setting up the topology state to crash.

Here is the backtrace from my PG18 beta1 VC++ EDB build.

As expected TopoGeo_LoadGeometry has the same issue:

SELECT TopoGeo_LoadGeometry('test', foo1.the_geom, 20.1)  As result
                                                        FROM ((SELECT '0101000020E6100000000000000000F07F000000000000F07F'::geometry AS the_geom ) ) As foo1 

and goes thru the same function.

same issue with ST_AddIsoNode, fails at same line
