I'm not sure adding a check would solve this. What should be done when a function with func_code=NULL is called? "Silently do nothing" is not really an option; raising an exception wouldn't help much in this case. I wonder if a function's tp_clear we should clear the mutable parts (like func_closure) before the immutable ones (func_code). Any access to the immutable ones should have checks (and probably raise exceptions if those are NULL).
