The following script exploits a comment in funcobject.c:
   /* XXX This is broken if the caller deletes dict items! */
Because the code only borrows references to the items, it is possible to
have them destroyed before they are copied into the called frame.

class Name(str):
  def __eq__(self, other):
     del x[self]
     return str.__eq__(self, other)
  def __hash__(self):
     return str.__hash__(self)

x = {Name("a"):1, Name("b"):2}
def f(a, b): print a,b

f(**x)   # Segfault
