Description:
------------
    Hi.  This is imacat from Taiwan.  I have reported a problem on static build before.  I saw you file it as #5763.

    I found that the PHP crack extension does not work on x86_64.  It returns "magic mismatch" when opening the dictionary.  The dictionary is fine, since pam_crack works with that dictionary.  I have tested this on my 2 x86_64 machines: The first one is Debian Sarge 3.1r4 AMD64, kernel 2.6.16.29, GCC 3.4.4, glibc 2.3.2, PHP 5.2.0.  The second is Debian Etch AMD64 d-i 2006-12-25, kernel 2.6.16.29, GCC 4.1.2, glibc 2.3.6, PHP 5.2.0.  The same code works fine on my i386/i686 machines.

Reproduce code:
---------------
#! /usr/bin/php
<?php
$dict = "/usr/share/dict/pw_dict";
$passwd1 = "analysis";
$passwd2 = "Dysk9queheoj";
echo "* crack_opendict(\"$dict\"):\n    ";
var_dump(crack_opendict($dict));
echo "* crack_check(\"$passwd1\"):\n    ";
var_dump(crack_check($passwd1));
echo "* crack_getlastmessage():\n    ";
var_dump(crack_getlastmessage());
echo "* crack_check(\"$passwd2\"):\n    ";
var_dump(crack_check($passwd2));
echo "* crack_getlastmessage():\n    ";
var_dump(crack_getlastmessage());
?>


Expected result:
----------------
On my i386/i686 machines:

imacat@leaf ~ % /tmp/test.php
* crack_opendict("/usr/share/dict/pw_dict"):
    resource(4) of type (crack dictionary)
* crack_check("analysis"):
    bool(false)
* crack_getlastmessage():
    string(32) "it is based on a dictionary word"
* crack_check("Dysk9queheoj"):
    bool(true)
* crack_getlastmessage():
    string(15) "strong password"
imacat@leaf ~ %


Actual result:
--------------
