PHP Bug Type: hash related
Bug description: The crc32b polynomial result has a wrong endianess
Description:
------------
The polynomial result of the crc32b hash function has since 5.2.8 a wrong
byte endianess on Windows. This also affects the CVS snapshot. I cannot
reproduce this error on any linux (debian / debian / gentoo / opensuse) box
I have, so I think this bug only affects Windows versions.
I tested different versions of PHP on my Windows system:
PHP 5.2.9RC4-dev (cli) (built: Feb 20 2009 15:57:39): affected
PHP 5.2.8 (cli) (built: Dec 8 2008 19:31:23): affected
PHP 5.2.6 (cli) (built: May 2 2008 18:02:07): NOT affected
The bug #45028 is maybe related to this one.
Reproduce code:
---------------
print hash('crc32b', 'Lorem Ipsum');
Expected result:
----------------
5dd48a35
Actual result:
--------------
358ad45d
