It doesn't matter what facilities you use. If you get libtiff to open a
bad TIFF file, it may well dump core. TIFF has been one of the most
abused standards over the years. It used to be that hardly any FAX
software would read the TIFFs produced by another package - both because
they were too stupid to read perfectly good TIFFs, and because many of
the TIFFs were not good. I used to have endless trouble with libtiff
dumping core on those bad TIFFs. If you have had no trouble, your TIFFs
must have lead a sheltered life :-)
