Description:
------------
A password_verify call with a second parameter value of null an error is reported in PHP 7 where none was thrown in PHP 5.5:

Example: "Deprecated: password_verify(): Supplied salt is not valid for DES. Possible bug in provided salt format. in /in/ThW5f on line 6"

http://3v4l.org/ThW5f

Test script:
---------------
<?php
// Run in current version of PHP 7

$input = 'test';
$hash = null;

$result = password_verify($input, $hash);
var_export($result);

Expected result:
----------------
false (as it was in PHP 5.5) as the string to verify isn't even valid

Actual result:
--------------
The way HHVM handles it would be nice:

Catchable fatal error: Argument 2 passed to password_verify() must be an instance of string, null given in /in/ThW5f on line 6
