[New-bugs-announce] [issue30567] Leak in sys.getwindowsversion

[Segev Finer]

New submission from Segev Finer:

There is a ref leak in sys.getwindowsversion due to using PyTuple_Pack and forgetting that it increments the ref count of passed in objects. Found here: https://github.com/python/cpython/pull/1927#issuecomment-306019512.

Clearly shows up in python -m test -R 3:2 test_sys
