New submission from Duncan Booth:
The following code throws a SystemError exception. cell_get_contents in
Objects\cellobject.c should check for a null op->ob_ref value and throw
an appropriate exception.
>>> def oops():
def f(): cell
f.func_closure[0].cell_contents
cell = None
>>> oops()
Traceback (most recent call last):
File "<pyshell#9>", line 1, in <module>
oops()
File "<pyshell#8>", line 3, in oops
f.func_closure[0].cell_contents
SystemError: error return without exception set
