[Gdal-dev] Re: [GDAL] #913: NITF driver fails for some CADRG tiles

[Even Rouault]

Sophia,

thanks for testing the fix for bug #913.
What's annoying is that I've just tested your file and it works fine with the 
svn version of GDAL trunk (as well as a version of GDAL 1.4.2 that I've 
patched). Just out of curiosity, I've removed the fix for bug #913 and 
another CADRG bug I've fixed, and your file is still working fine...
Even more, it is still working fine with the official GDAL 1.4.2 release. Are 
you really sure you're linking with the good GDAL library ?
I can't see other explanations for the moment.

Your first message said that the bbox displayed was not correct. I get the 
following results with GDAL svn trunk :
