This is what is happening when GraphicsMagick writes the TIFF.
Before I reverted my (apparently) improper cast, this is what happened when tiffcp wrote a file as well.
% tiffdump -m 1000 tiger-rgb-strip-contig-08.tif
tiger-rgb-strip-contig-08.tif:

Is no one else seeing this problem? Libtiff 3.9.0 was released on the 20th.
