[gdal-dev] NITF Int16 image size limit

[Even Rouault]

Please keep the mailing list copied (I re-added it)

This is not the most recent one (3.2.2 is), but skimming quickly through 
release notes, I can't see anything directly related, so it might still 
be current with the recent versions. Altough I see that a bunch of 
"avoid unsigned integer overflow" type of fixes have been done since 
2.4, so some of them might have accidentally fixed the issue.

If you can try with the latest version ( Docker images mentioned at 
https://github.com/OSGeo/gdal/tree/master/gdal/docker, Conda, etc .), 
that could be interesting.
