To reproduce: $ tiffcp -c jpeg k2a.tif x.tif (where k2a.tif is a simple uncompressed RGB strip tiff) appears to work. However, x.tif, the output, will now not read without warnings: $ tiffcp x.tif y.tif TIFFFetchNormalTag: Warning, ASCII value for tag "JPEGTables" does not end in null byte. Forcing it to be null. JPEGLib: Warning, Premature end of JPEG file. This was working fine until a couple of days ago, so I guess it's one of the most recent patches. Some packages using libtiff seem to be broken too. For example, openslide, which uses libtiff to load jp2k-compressed slide images, is no longer working: $ openslide-write-png CMU-1-Small-Region.svs 0 0 0 100 100 x.png TIFFFetchNormalTag: Warning, ASCII value for tag "JPEGTables" does not end in null byte. Forcing it to be null. TIFFFetchNormalTag: Warning, ASCII value for tag "JPEGTables" does not end in null byte. Forcing it ... repeats 8 more times openslide-write-png: Premature end of JPEG file and x.png is not a valid PNG image.
