checkHash returns true for different passwords

Hello there. I have a very strange trouble with Security checkHash function. It returns true for different passwords. Maybe it depends on algo?..

There is a code:

        $service = new Security;

        var_dump($service->getDefaultHash());

        var_dump($service->hash('qwerty1231112asdadfaf!!!'));
        var_dump($service->checkHash('qwerty1231112asdadfaf!!!11', 'bmwxO.XvhuckM'));

Value "bmwxO.XvhuckM" was returned by hash function on first start of this snippet.

Result:

/git/app/index.php:161:null
/git/app/index.php:163:string '$2y$10$VStBNndBVmMzcTBJTWlmOO3S834G97VpMWN58oQ0COBW5VouL1kh.' (length=60)
/git/app/index.php:164:boolean true

Same result with CRYPT_SHA512:

        $service = new Security;
        $service->setDefaultHash(Security::CRYPT_SHA512);

        var_dump($service->getDefaultHash());

        var_dump($service->hash('qwerty1231112asdadfaf!!!'));
        var_dump($service->checkHash('qwerty1231112asdadfaf!!!11', 'bmwxO.XvhuckM'));

Result:

/git/app/index.php:162:int 9
/git/app/index.php:164:string '$6$Y0xLZHZuZWcrSG9s$8c/GXCH.yJCJaf6abjhM33NrgOnANmbC5kQ9y5.VEx3w/bbhAWNgWomTmSm1KUgDHIefhlVADfxUjbPP9tYKJ0' (length=106)
/git/app/index.php:165:boolean true

What's may be wrong? Thanks.
