Seems related to 
http://svn.php.net/viewvc/php/php-src/branches/PHP_5_4/ext/hash/hash_tiger.c?r1=321634&r2=322437

(8 * (0%8)) != 56


The patch fixes this, and the "old" tests.

I think, this will break the "new" tests (added after the regression was introduce)

To clarify the situation, it's just a matter of how to display the hash:

 [2012-03-06 18:13 UTC] remi@php.net 
So, to clarify the fix for bug #60221

The new result is ok.

So, mhash_001.phpt and mash_003.phpt tests need to be fixed

So, if I have store hash results somewhere with php < 5.4.0, I won't be able to check this with php >= 5.4.0 ?
