[New-bugs-announce] [issue14815] random_seed uses only 32-bits of hash on Win64

[Martin v. Löwis]

New submission from Martin v. Löwis <martin at v.loewis.de>:

random_seed has this code:

  long hash = PyObject_Hash(arg);

On Win64, Py_hash_t is a 64-bit type, yet long is a 32-bit type, so this truncates. I think the computation should be done in Py_ssize_t.
