[Gdal-dev] crash ( access violation ) in GDAL when trying to read a TIFF

[Stephane Routelous]

Hi Andrey,

I got the daily cvs snapshot (gdal-cvs-20040902), recompiled it in debug,
and still got the same problem.
Here is my test code :
int main(int argc, char* argv[])
{
	GDALAllRegister();
	GDALDataset* m_gdalDataSet = (GDALDataset *) GDALOpen(
"C:\\TestDB\\cramps-tile.tif", GA_ReadOnly );  //this is line 15
	cout << m_gdalDataSet->GetRasterXSize() << " " <<
m_gdalDataSet->GetRasterYSize() << endl;
	GDALClose(m_gdalDataSet);
	return 0;
}

I hope the following information will be usefull :
Thnaks a lot,

Stephane
