This still exists with 0.10.0, and this is not specifically due to the RPF A.TOC format, but the crash can happy with any raster format that declare subdatasets (HDF4, HDF5, OGDI raster, netCDF, RS2 and ADRG drivers are also concerned by this). The main raster has no data itself, but declares a list of subdatasets that can be opened by GDALOpen.
Here's the stack trace of the crash
Program received signal SIGABRT, Aborted.

In fact, this is due to the following code snipet that makes the assumption that the return of GDALGetRasterBand(hDS, 1) will be non-NULL.
//check f this file has pyramids
GDALRasterBandH myGDALBand = GDALGetRasterBand( mGdalDataset, 1 ); //just use the first band
if( GDALGetOverviewCount(myGDALBand) > 0 )
{
hasPyramidsFlag=true;
}
else
{
hasPyramidsFlag=false;
}
The quickest fix is to apply the attached patch. In a longer term, it may be good to support subdatasets, by displaying the list of subdatasets to the user, as [[OpenEV]] does.

When I try to add a raster layer and select RPF>A.TOC file the entire program closes out without any warning or anything. This occurs on both the windows version and Linux version that I am using. This map data is good. It was download striaght from NGA website on a secret network.
