[gdal-dev] Segmentation fault with debian install of gdal on
MODIS hdf4 files

Thanks, but I was hoping someone had seen this with the latest Debian
release. Follow-up question, if I were to uninstall gdal + all the
affiliated libraries/dependencies, what do I need to make sure I
remove? I'm noticing, at least, that the segfault is not occurring on
another debian box we have -- seems like something may have gotten
corrupted along the way, but I've tried doing an apt-get remove on
libgdal1-dev and gdal-bin, as well as the libhdf4. Any tricks to
"clearing out" gdal for a "clean" reinstall?
