Description
See the attached shapefile. There is a problem with the geometry of the last feature.
Try to extract the zip file in a folder and
ogrinfo /your/folder -sql "SELECT * FROM poly"
You can see this error for the last feature:
ERROR 1: Error in fread() reading object of size 276 from .shp file
NOTE: If I open this shapefile with ESRI ArcMap there is no problem.
Where is the problem? Is the shapefile corrupted? Is a problem of the ogr library?
Thanks in advance,
michele

Cuplicate to a fixed issue #5608 http://trac.osgeo.org/gdal/ticket/5608
Summary: Caused by a bug that was present in shapelib till version 1.2.7 http://shapelib.maptools.org/release.html
Note:
See TracTickets
for help on using tickets.
The last .shx entry references an object of 268 bytes at offset 28248 (plus 8 bytes of header info) so it does appear to extend past the end of the .shp file which is only 28480 bytes long. I suspect the object header in the .shp file references a shorter length for the actual object but I don't have time this morning to confirm this. I'll dig more later.
