[Gdal-dev] about VRTDataset

[Fu Chen]

Frank,

I also find it very weird. I compile gdal and my test program on two PC has the same result. 
The gdal is cleaned by "nmake /f makefile.vc clean", and rebuild several times. But still has trouble.
even this code won't work

#include "cpl_vsi.h"
#include "cpl_conv.h"
#include "cpl_string.h"
#include "gdal_priv.h"
#include "ogr_spatialref.h"
#include "vrt/vrtdataset.h"

void main()
{
    //GDALAllRegister();
    VRTDataset *poVDS;
    poVDS = new VRTDataset( 100, 100);
 //GDALDumpOpenDatasets( stderr );
 delete poVDS;
}

The Debug said
HEAP[translate.exe]: Invalid Address specified to RtlFreeHeap( 12b0000, 12c3a28 )
at the end of delete statement.

I really don't know what's wrong. Maybe a bug in vc compiler :<
