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 :-)
