Is this result for hash('') expected?

That's weird:

$ pypy
Python 2.7.13 (3fbdd036db1c, Feb 26 2017, 23:00:12)
[PyPy 5.7.0-alpha0 with GCC 4.8.2] on linux2
Type "help", "copyright", "credits" or "license" for more information.
And now for something completely different: ``< arigato> then what occurs? <
fijal> good stuff I believe''
>>>> hash("")
-2

Where did you get your pypy from?

It's a squeaky_pl portable build. pypy56 has hash('') == -2, but I normally test against 5.3.
