This isn't really a bug, it's more of a different  
implementation/interpretation of the Tiger algorithm. The  
test vectors provided on the Tiger homepage provide the  
output hash in little endian, while the testtiger  
reference implementation at the site outputs the hash in  
big endian. Both outputs are correct, I guess, it's just  
the ordering of the bytes that changes.   
  
I'll leave the bug status as is so Sascha can see it and 
give a more definitive anwser than I can, but I don't 
think it's a bug per se.
