At r32878 (git 1eb605a), Even added new logic for dealing with raw 32-bit AIG blocks. I've got an AIG raster that has a few blocks where valid data is getting set to the min Int32 value (-2147483648) when doing a gdal_translate to GeoTiff. gdal_translate -of GTiff ai_bug ai_bug.tif Note the ""old"" way of getting these values was providing the correct values in this case: panData[i] = pabyCur[0] * 256 * 256 * 256 + pabyCur[1] * 256 * 256 + pabyCur[2] * 256 + pabyCur[3] + nMin; Note that this is only affecting selected blocks within the raster. Other blocks seem to be just fine. Test raster posted here: ftp://ftp.fsl.orst.edu/pub/gregorym/gdal/ai_bug.7z (1MB) From my testing, <= 2.0 is OK, >= 2.1 is affected. Tested on Windows 10 64-bit. }}}" defect closed normal 2.1.4 default 2.1.0 normal fixed aig
