#4203 closed defect (fixed)

Error in fread() reading object from shp file

Reported by: zanollim Owned by: warmerdam
Priority: normal Milestone: 2.0.0
Component: OGR_SF Version: 1.8.1
Severity: normal Keywords: Shapefile


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,

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.
