But some programs that need to use both gdal and geotiff explicitly have no choice. Due to the with-hide-internal-symbol they can't access to the geotiff methods from gdal: linking to geotiff explicitly is no longer an option. According to more extensive tests that make full use of the tiff/geotiff structure, the ubuntu version does not seem to trash things (262 of the OTB tests that segfault on Debian are successful on Ubuntu).
