[Gdal-dev] MrSID Segmentation Fault

[Simpson]

Hi,

I have successfully got gdal utilities to process the majority of my sid
files, but landsat data from https://zulu.ssc.nasa.gov/mrsid/ is getting
segmentation fault.  The MrSID utilities mrsidinfo and mrsiddecode seem to
work properly with these datasets.  The one I've been playing with is
https://zulu.ssc.nasa.gov/mrsid/bin/download_file.pl?client=etmpsmos/sid&ima
ge=N-16-30_2000.tar , if you can get through to the site.  Any
tips/suggestions would be great.

Thanks,
Drew.




System Info
	Linux xxxx 2.4.20-20.8 #1 Mon Aug 18 14:59:07 EDT 2003 i686 i686 i386
GNU/Linux

GCC Info
	gcc version 3.2 20020903 (Red Hat Linux 8.0 3.2-7)

GDAL Info
	I tried both gdal-1.2.1 and the csv gdal-cvs-20040903

	configuration
		./configure
			--with-mrsid=/usr/local/Geo_DSDK-4.0.9.713
			--without-geos
			--with-geotiff=internal

	The geotiff on the system would not compile so used version that came with
gdal.
	As soon as I can get my paws on a newer geotiff, I will install it.  Darn
hurricanes!

MrSID Info
	Geo_DSDK-4.0.9.713
