HDF4 EOS case EOS GRID memory error.

[denis.nadeau@…]

hdf4imagedataset.cpp line 2221
poDS->iBandDim = i;

When Dimension List does not have the word "Band", this variable never get set and it is initialized to -1 in the constructor.  This cause a memory error in IReadBlock method.

hdf4imagedataset.cpp line 429
aiStart[poGDS->iBandDim] = nBand - 1;
aiEdges[poGDS->iBandDim] = 1;

aiEdges[-1]=1  on my machine cause eERR variable to be set to CPL_DEBUG and causing a faulty GDAL Read error, for eERR should be CPL_None when IReadBlock returns.

I guess in the 3D array case this should be set to 0.

This condition works for me.  I assume that X and Y dimension will
have X or Y in there name.

                    for ( i = 0; i < nDimCount; i++ )
                    {
                        if ( !(strstr( papszDimList[i], "X" )) &&
			     !(strstr( papszDimList[i], "Y" )) )
                        {

Denis,

I ran into this today, and put a bunch of fixes in related to this area of code.

Can you verify that the trunk version of GDAL fixes the problem you were seeing?
