New submission from Marc Schlaich:
This simple test case results in a lib2to3 crash with an AssertionError in
2.7.11
source = '''
class Test(object):
tests = []
'''
from lib2to3.refactor import RefactoringTool
def main():
tool = RefactoringTool([])
tool.refactor_string(source, '')
Exception:
Traceback (most recent call last):
File "test.py", line 21, in <module>

File "test.py", line 16, in main

AssertionError
Pretty weird: A manually built Python 2.7.11 with VS 2008 doesn't show this
issue.
