Description:
------------
crypt() seems to be breaking for some reason with this password and salt combination

I've not read anything about limitations on the characters supplied to crypt() in the PHP documentation

Test script:
---------------
<?
$plain = "W9no`y_vr.!b<W'.Wp44NU~\"Vf}n{G077<^UnqFyWwKyaz1YuyrO9H+1/T8J3Ha_C|X=gU^?EBrc2";
$salt = '$2a$10$CqenGirJlEl6sCA2/w2ay';

echo crypt($pre, $salt);
?>

Expected result:
----------------
$2a$10$CqenGirJlEl6sCA2/w2a (followed by hashed data)

Actual result:
--------------
*0

After all that concern of an unknown buffer overflow or disallowed character, I forgot to end the salt with a $ character :(
