for big geotiff files the tiling craches due to negative values in rxsize, rysize, wxsize, wysize. We just skip the inopropriate tile sizes.

@antonmyagotin https://gis.stackexchange.com/questions/249809/gdal2tiles-error-5-illegal-values-for-buffer-size-error-for-a-single-zoom-lev is about size = 0. Do you have a reproducer with negative sizes ? |

Please use "gdal_create" with options "-co TILED=YES -co SPARSE_OK=YES" to create an empty file with the same characteristics, and attach it there (zipped), and also the exact gdal2tiles command line you use |

Problem:
Gdal2tiles crashes with the message "Illegal values for buffer size". The problem was reported in multiple source and exists already for years. Examples:
https://gis.stackexchange.com/questions/249809/gdal2tiles-error-5-illegal-values-for-buffer-size-error-for-a-single-zoom-lev
Solution:
We just skip the tile with negative extent values.
