[gdal-dev] SAGA: problem to convert grid from ETRS 89 / ETRS-LAEA to WGS84 CRS

[Volker Wichmann]

This seems to me like an integer overflow - looking at the GDAL 1.7.2 
sources I see, that the WriteHeader() method of sagadataset.cpp is using

GInt16 nXSize, GInt16 nYSize

Most likely this should be changed to

int nXSize, int nYSize


Best regards,
Volker
