There was a problem hiding this comment.
The get_code() function was added to the _frozen structure in Python 3.11. New C API functions must no longer return borrowed references, but strong references: https://devguide.python.org/c-api/#public-c-api
Would it be possible to change the generated code to return strong references instead? I don't understand how deepfreeze generates its "get_code()" functions.
