Crashes in DEMToImageGenerator
DEMToImageGenerator crashes randomly, this has been observed on ioTvDEMToImageGeneratorFromImageTest and ioTvDEMToImageGeneratorFromImageTest2 tests on CI. This might also be the cause of this issue (DEM example)
I think it is caused by the fact that OGRCoordinateTransformation is not thread safe, but the same OGRCoordinateTransformation is used by different threads in DEMToImageGenerator.
