[gdal-dev] Problem with gdalsrsinfo on some NOAA bsb/kap files

[Robb Wright]

I just tried it on another machine on a number of .kaps - and some were 
working and some were not - but they were different ones. Then I went 
back to my first machine and I got the proper result, then ran it again 
and got the error.  Something must be dodgy with my libraries/how I have 
it installed, but I can't imagine why it would work some times and not 
others on the same file.

If somebody else could try running it multiple times on the same file, 
I'd be curious about their result.  Below is a link to a set of 4.  
Right now I'm getting errors on _1, _2 - but getting results for 
_3,_4.    Nutty.
http://www.charts.noaa.gov/RNCs/11308.zip
gdalsrsinfo.exe -o proj4  11308_1.KAP
gdalsrsinfo.exe -o proj4  11308_2.KAP
gdalsrsinfo.exe -o proj4  11308_3.KAP
gdalsrsinfo.exe -o proj4  11308_4.KAP

BTW, I'm using gdalsrsinfo from today's 
http://www.gisinternals.com/sdk/PackageList.aspx?file=release-1600-x64-gdal-1-9-mapserver-6-0.zip
