[New-bugs-announce] [issue40451] Unexpected sys.getrefcount(foo) output

[Cristian Martinez de Morentin]

New submission from Cristian Martinez de Morentin <cmartinez at das-nano.com>:

Hello, I have observed a strange behaviour regarding reference counting in Python 3.8.2 (Windows 64 bits). Perhaps, it could be linked to a memory leakage issue.

In the following code, I would not expect an output of '137' for the reference counter of the 'aux' object. Could you please explain this behaviour?

>>> import sys
>>> test = {'a': 0, 'b': 1}
>>> sys.getrefcount(test)
2
>>> aux = test['b']
>>> sys.getrefcount(aux)
137

Thank you so much.
