  #3479: unichr(2**32) used to return u'\x00'.
  The argument was fetched in a long, but PyUnicode_FromOrdinal takes an int.

  (why doesn't gcc issue a truncation warning in this case?)

  Correct a crash when two successive unicode allocations fail with a MemoryError:
  the freelist contained half-initialized objects with freed pointers.

  The comment

  was copied from tupleobject.c, and appears in some other places.
  I sign the petition.
