[gdal-dev] Re: Bug(?): RIK-maps with Gdal 1.7.2 do not work

[Tomas R]

  I add - perhaps a problem with my comilation of Gdal.  Note when I 
compile the GdalReadDirect.cs as it is and run it the result differs 
from the result of the GdalReadDirect.exe found in Swig\Csharp.
The latter gives the Raster dataset Paramets and runs until an Out of 
memory Exception. Mine hangs and I have to abort it.

What have I done wrong this time?

Will try to recompile gdal and see if anything changes.
