[New-bugs-announce] [issue29864] Misuse of Py_SIZE in dict.fromkey()

[Serhiy Storchaka]

New submission from Serhiy Storchaka:

In dict.fromkeys() implementation when a dict is passed its size is determined by using the Py_SIZE macro. This is not correct since PyDictObject is not a PyVarObject (but see issue28988).
