import atexit
atexit.register(your_cleanup_function)

whose api is no args on input:

def your_cleanup_function():
  do_whatever...


You could use here a little extension function which goes in and does
the necessary free() calls on a pre-stored list of allocated pointers,
if there's more than one (I don't really know what's going on here).
