Cannot verify the password after hashing

[jackyshek]

I have tested the password_verify of PHP that does not verify correctly. I am using centOS and PHP version 5.3.3.
It is always to return true with different passwords when i verify it. Is my code has bug?

Here is my code:

$password = 'k32AlGOPqvCzoh*Sp(Hdrr26]M=lQb00R&W=hew|-|([(03vp==A8%m?l=eA2^bs_|\qVV3WZ';

$verify_pw = 'k32AlGOPqvCzoh*Sp(Hdrr26]M=lQb00R&W=hew|-|([(03vp==A8%m?l=eA2^bs_|\qVV3WZasdasdasdasdqweqa13123';

$options = array(
            'cost' => 15
        );

$hash = password_hash($password, PASSWORD_BCRYPT,$options);

var_dump(password_verify($verify_pw ,$hash)); // sometime true sometime false

From the requirements on the homepage:

This library requires PHP >= 5.3.7 OR a version that has the $2y fix backported into it (such as RedHat provides). Note that Debian's 5.3.3 version is NOT supported.
