phpass: why would HashPassword fail?

I'm reading phpass manual. At some point, it checks the result of the hashing like this:

$hash = $hasher->HashPassword($pass);
if (strlen($hash) < 20)
    fail('Failed to hash new password');

I understand that's the minimum lenght for a phpass hash, but I don't understand why would it fail. Is it even possible? I mean, who/what should I blame if it happens? How to prevent that? I also posted a comment about this in the web page.

For reference, you can find the code of PasswordHash::HashPassword() in this question: How can * be a safe hashed password?

I noticed that some underlying libraries, such as 'crypt' don't fail gracefully when something is wrong, but just return a shorter string.

Maybe this is a symptom of this problem, and just an extra precaution.
