#47467 [NEW]: The crc32b polynomial result has a wrong endianess

From: php at twinmail dot de Operating system: Windows XP SP2 PHP version: 5.2.8 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 -- Edit bug report at http://bugs.php.net/?id=47467&edit=1 -- Try a CVS snapshot (PHP 5.2): http://bugs.php.net/fix.php?id=47467&r=trysnapshot52 Try a CVS snapshot (PHP 5.3): http://bugs.php.net/fix.php?id=47467&r=trysnapshot53 Try a CVS snapshot (PHP 6.0): http://bugs.php.net/fix.php?id=47467&r=trysnapshot60 Fixed in CVS: http://bugs.php.net/fix.php?id=47467&r=fixedcvs Fixed in CVS and need be documented: http://bugs.php.net/fix.php?id=47467&r=needdocs Fixed in release: http://bugs.php.net/fix.php?id=47467&r=alreadyfixed Need backtrace: http://bugs.php.net/fix.php?id=47467&r=needtrace Need Reproduce Script: http://bugs.php.net/fix.php?id=47467&r=needscript Try newer version: http://bugs.php.net/fix.php?id=47467&r=oldversion Not developer issue: http://bugs.php.net/fix.php?id=47467&r=support Expected behavior: http://bugs.php.net/fix.php?id=47467&r=notwrong Not enough info: http://bugs.php.net/fix.php?id=47467&r=notenoughinfo Submitted twice: http://bugs.php.net/fix.php?id=47467&r=submittedtwice register_globals: http://bugs.php.net/fix.php?id=47467&r=globals PHP 4 support discontinued: http://bugs.php.net/fix.php?id=47467&r=php4 Daylight Savings: http://bugs.php.net/fix.php?id=47467&r=dst IIS Stability: http://bugs.php.net/fix.php?id=47467&r=isapi Install GNU Sed: http://bugs.php.net/fix.php?id=47467&r=gnused Floating point limitations: http://bugs.php.net/fix.php?id=47467&r=float No Zend Extensions: http://bugs.php.net/fix.php?id=47467&r=nozend MySQL Configuration Error: http://bugs.php.net/fix.php?id=47467&r=mysqlcfg
