I also looked at LibTIFF 4.0.4beta last night, and the test passes there.
It looks like they're trying to test the expected output of specific jpeg
lib versions, and have changed the test to look at ranges of acceptable
values instead. Copying just the test/raw_decode.c from LibTIFF-4.0.4beta
to 4.0.3 allows all tests to pass on 4.0.3.
