[gdal-dev] Attempt to read past EOF ... dtm000082/../info/arc.dir

[Markus Neteler]

Hi,

I have received a set of (official governmental) DTM files which all
report subsequent errors:

gdalinfo /home/neteler/data/DTM_wgs84_orto_grd/B_1mX1m/dtm000082
ERROR 3: Attempt to read past EOF in

GDAL is luckily able to extract the data anyway but it doesn't look well.
My question is if this could be a GDAL problem or rather a broken
data set (I have 1750 of them). Before notifying them I want  to be sure
that GDAL operates ok.

thanks,
Markus
