[gdal-dev] Error in fread() reading object from shp file

[Pedro Venâncio]

Hi all,

It seems that this question raised up again in GDAL/OGR 2.3.2:

https://trac.osgeo.org/gdal/ticket/4203

I've a shapefile produced in a old version of gvSIG, that worked well in
QGIS 2.18.24, compiled against GDAL/OGR 2.2.4 on Windows, and 2.2.2 on
Linux.

After update to QGIS 2.18.25 and QGIS 3.4, that were compiled against
GDAL/OGR 2.3.2, the geometry of the shapefile is not visible, just the
attributes.

ogrinfo shows the ERROR 1: Error in fread() reading object of size 776 at
offset 100 from .shp file

ogrinfo -al Isocronas_RV_Manteigas_Linhas_gvSIG.shp

The shapefile is this one:

Is this a problem from GDAL/OGR?

Thank you very much!
