I can replicate the crash with the JP2ECW driver with ECW SDK 3.3. It occurs actually in the SDK itself, not in GDAL, so nothing that we can really do about that (except using GDAL API Proxy, see below). Newer versions of the SDK don't produce this crash. Frank's above suggestions are the way to go. Tamas' builds do include MrSID support as a plugin (XXXX-mrsid.msi packages). But they also include the OpenJPEG driver, which can successfully open this file and should be the next driver used after skipping JP2ECW : $ gdalinfo --config GDAL_SKIP JP2ECW IMG_PHR1A_MS_201202250025599_SEN_PRG_FC_5847-002_R1C1.JP2 Driver: JP2OpenJPEG/JPEG-2000 driver based on OpenJPEG library Files: IMG_PHR1A_MS_201202250025599_SEN_PRG_FC_5847-002_R1C1.JP2 IMG_PHR1A_MS_201202250025599_SEN_PRG_FC_5847-002_R1C1.JP2.aux.xml Size is 10000, 6191 Coordinate System is `' GeoTransform = 144.8407819720184, 2.303727068124578e-05, -3.011809327220197e-09 -37.76248166104331, -9.154071614724073e-09, -1.808332187648097e-05 Image Structure Metadata: INTERLEAVE=PIXEL Corner Coordinates: Upper Left ( 144.8407820, -37.7624817) Lower Left ( 144.8407633, -37.8744355) Upper Right ( 145.0711547, -37.7625732) Lower Right ( 145.0711360, -37.8745270) Center ( 144.9559590, -37.8185044) Band 1 Block=2048x2048 Type=UInt16, ColorInterp=Red Overviews: 5000x3095, 2500x1547, 1250x773, 625x386, 312x193 Overviews: arbitrary Image Structure Metadata: NBITS=12 Band 2 Block=2048x2048 Type=UInt16, ColorInterp=Green Overviews: 5000x3095, 2500x1547, 1250x773, 625x386, 312x193 Overviews: arbitrary Image Structure Metadata: NBITS=12 Band 3 Block=2048x2048 Type=UInt16, ColorInterp=Blue Overviews: 5000x3095, 2500x1547, 1250x773, 625x386, 312x193 Overviews: arbitrary Image Structure Metadata: NBITS=12 Band 4 Block=2048x2048 Type=UInt16, ColorInterp=Alpha Overviews: 5000x3095, 2500x1547, 1250x773, 625x386, 312x193 Overviews: arbitrary Image Structure Metadata: NBITS=12 If you want to use the JP2MrSID driver, you need to set --config GDAL_SKIP "JP2ECW JPEG2000 JP2OPENJPEG" > Dennis, > I believe you can use Even's GDAL API Proxy to avoid crashes in third >party libraries.
