New submission from Bogdan Opanchuk <[email protected]>:
Tested on PyPy-2.2.1
Code:
import copy
import ast
func = ast.FunctionDef(
name='__wrapper',
args=ast.arguments(args=[], vararg=None, kwarg=None, defaults=[]),
decorator_list=[],
body=[ast.Pass()])
func2 = copy.deepcopy(func)
The last line raises the following exception:
Traceback (most recent call last):
File "app_main.py", line 72, in run_toplevel
File "t2.py", line 10, in <module>
func2 = copy.deepcopy(func)
File "/Users/bogdan/.pyenv/versions/pypy-2.2.1/lib-python/2.7/copy.py",
line 182, in deepcopy
rv = reductor(2)
AttributeError: 'FunctionDef' object has no attribute 'lineno'
No exception is raised in CPython 2.7.6 and 3.4.0.
