[New-bugs-announce] [issue33309] Unittest Mock objects do not freeze arguments they are called with

[Nathaniel Duarte]

New submission from Nathaniel Duarte <slacknate at gmail.com>:

It is possible to make a call with a Mock object, for example, where a dictionary is passed to the mock and later modified. If a call assertion is then made against the mock using the initial value/contents of the dictionary the assertion will fail.
