[gdal-dev] Error reading long numbers as integer

Yes, this is an issue that can be potentially found in other drivers. The 
situation could improve if/when RFC 31 / OGR 64bit integer is adopted.

For the time being, I've made a change in the GML driver so that it fallbacks 
to Real when it detects an integer that cannot fit into 32bit. Not ideal, but 
better than arbitrary truncation.

Which change did you make exactly ? Change from Integer to Real ?

I'm a bit skeptical about that one. Which exact commands did you use ?
