I believe the line table format got changed but the frozen code didn't get re-generated. If you try to call co_lines() on the __hello__ code, Python crashes. >>> import __hello__ Hello world! >>> co = __hello__.__spec__.loader.get_code('__hello__') >>> co.co_linetable b'\x04\x01' >>> list(co.co_lines()) python: ../Objects/codeobject.c:1185: PyLineTable_NextAddressRange: Assertion `!at_end(range)' failed. My PR re-generates the code and fixes the test. Perhaps I should also add a test to exercise co_lines() on the frozen code object.

>>> import __hello__
Hello world!
>>> co = __hello__.__spec__.loader.get_code('__hello__')
>>> co.co_linetable
b'\x04\x01'
>>> list(co.co_lines())
python: ../Objects/codeobject.c:1185: PyLineTable_NextAddressRange: Assertion `!at_end(range)' failed.
