[New-bugs-announce] [issue17932] Win64: possible integer overflow in iterobject.c

[STINNER Victor]

New submission from STINNER Victor:

seqiterobject.it_index type is long, whereas iter_setstate() uses a Py_ssize_t. It would be safer to use Py_ssize_t type for seqiterobject.it_index.

The issue emits a compiler warning on Windows 64-bit.

iterator.__getstate__() was introduced in Python 3.3, so older versions are not affected.
