[New-bugs-announce] [issue17645] assert fails in _Py_Mangle

[Armin Rigo]

New submission from Armin Rigo:

Run this example on a 32-bit machine with more than 2GB of addressable RAM (e.g. by default, more or less anything but Windows).

On Python 2.7 it raises "SystemError: Negative size passed to PyString_FromStringAndSize".  On a debug version, it causes an assert in _Py_Mangle() to trigger.
