It does not reproduce on any released versions of Python interpreter.

It's likely related to this entry in core changelog:

Module, FunctionDef, AsyncFunctionDef, and ClassDef AST nodes now have a new docstring field. The first statement in their body is not considered as a docstring anymore. co_firstlineno and co_lnotab of code object for class and module are affected by this change.
