Hi Remi,

this is not a bug, it's the result of a fix for bug #60221
See alos bug #32463

Thanks,
Mike

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)
