Hum, Python 3.7 is fixed as well. At least, in the 3.7 dev branch.
Fixed seed:
vstinner@apu$ PYTHONHASHSEED=42 ./python -c 'print(set("abcdefgh"))'
{'g', 'e', 'a', 'b', 'c', 'f', 'h', 'd'}
vstinner@apu$ PYTHONHASHSEED=42 ./python -c 'print(set("abcdefgh"))'
{'g', 'e', 'a', 'b', 'c', 'f', 'h', 'd'}
vstinner@apu$ PYTHONHASHSEED=42 ./python -c 'print(set("abcdefgh"))'
{'g', 'e', 'a', 'b', 'c', 'f', 'h', 'd'}
vstinner@apu$ PYTHONHASHSEED=42 ./python -c 'print(set("abcdefgh"))'
{'g', 'e', 'a', 'b', 'c', 'f', 'h', 'd'}
Random seed:
vstinner@apu$ PYTHONHASHSEED=42 ./python -I -c 'print(set("abcdefgh"))'
{'b', 'e', 'd', 'f', 'g', 'c', 'a', 'h'}
vstinner@apu$ PYTHONHASHSEED=42 ./python -I -c 'print(set("abcdefgh"))'
{'d', 'g', 'e', 'b', 'h', 'f', 'a', 'c'}
vstinner@apu$ PYTHONHASHSEED=42 ./python -I -c 'print(set("abcdefgh"))'
{'e', 'b', 'g', 'c', 'a', 'h', 'f', 'd'}
vstinner@apu$ PYTHONHASHSEED=42 ./python -I -c 'print(set("abcdefgh"))'
{'c', 'd', 'a', 'g', 'f', 'e', 'h', 'b'}

Python 3.6 has the bug:
vstinner@apu$ PYTHONHASHSEED=42 python3.6 -c 'print(set("abcdefgh"))'
{'g', 'e', 'a', 'b', 'c', 'f', 'h', 'd'}
vstinner@apu$ PYTHONHASHSEED=42 python3.6 -c 'print(set("abcdefgh"))'
{'g', 'e', 'a', 'b', 'c', 'f', 'h', 'd'}
vstinner@apu$ PYTHONHASHSEED=42 python3.6 -c 'print(set("abcdefgh"))'
{'g', 'e', 'a', 'b', 'c', 'f', 'h', 'd'}
vstinner@apu$ PYTHONHASHSEED=42 python3.6 -c 'print(set("abcdefgh"))'
{'g', 'e', 'a', 'b', 'c', 'f', 'h', 'd'}
vstinner@apu$ PYTHONHASHSEED=42 python3.6 -I -c 'print(set("abcdefgh"))'
{'g', 'e', 'a', 'b', 'c', 'f', 'h', 'd'}
vstinner@apu$ PYTHONHASHSEED=42 python3.6 -I -c 'print(set("abcdefgh"))'
{'g', 'e', 'a', 'b', 'c', 'f', 'h', 'd'}
vstinner@apu$ PYTHONHASHSEED=42 python3.6 -I -c 'print(set("abcdefgh"))'
{'g', 'e', 'a', 'b', 'c', 'f', 'h', 'd'}
vstinner@apu$ PYTHONHASHSEED=42 python3.6 -I -c 'print(set("abcdefgh"))'
{'g', 'e', 'a', 'b', 'c', 'f', 'h', 'd'}
