ZM Shapefiles fail to parse #1

Typical of files digitized in Google Earth and processed from KML to shape. Problem persists across conversion and is difficult to diagnose.

Expected behavior: should reject with appropriate error message, or force conversion to simple features.

According to:
https://gis.stackexchange.com/questions/166523/remove-3d-geometry-in-shapefile-using-ogr
could use:
ogr2ogr -f "ESRI Shapefile" output_2d.shp input_zm.shp -dim 2
where -dim 2 strips the unwanted dimensions.

Example file with this problem:
shapefiles/aggregationlayers/Pivot_Pamplona2.zip
