Tom, I haven't dug through the previous emails closely to see what is going on, but I thought I should answer this. There has been a substantial improvement in the amount of precision OGR maintains for WKT and GML encodings of geometries. The changes were applied a couple months ago. They are definately in GDAL/OGR 1.3.1 and might be in 1.3.0. OGR spatial filtering will also now use GEOS if built-in. It is possible that some "on the edge" situations would give different results now compared to in the past. I'm not sure if any of this relates to the problem you are seeing though.
