利用Gdal读取tif文件，获取图像的行列时，发生访问冲突，具体代买如下

void CGeoCorrectionDoc::Load_dem()
{
static char BASED_CODE file[] = "TIF Files(*.tif)|*.tif|所有文件(*.*)|*.*||";
CString strFilePath;
CFileDialog dlg(TRUE,"tif",NULL,OFN_HIDEREADONLY|OFN_OVERWRITEPROMPT,file,NULL);
// CDEMImport dlg(FALSE,"bmp",NULL,OFN_HIDEREADONLY|OFN_OVERWRITEPROMPT,file,NULL);
if (dlg.DoModal() == IDOK)
{
strFilePath = dlg.GetPathName();
}
else return;
GDALDataset poDataSet;
GDALAllRegister();
poDataSet=(GDALDataset)GDALOpen(strFilePath,GA_ReadOnly);
SizeX=poDataSet->GetRasterXSize();//该位置发生访问冲突，提示在gdal203处引发的异常
SizeY=poDataSet->GetRasterYSize();
dem_temp=new float [SizeX*SizeY];
