test_clear_pickler_memo tested only the default protocol and fails when bump the default protocol to 4. For some reasons C implementation writes FRAME before PROTO when call Pickler.dump() repeatedly.

Python implementation:
b'\x80\x04\x95\x13\x00\x00\x00\x00\x00\x00\x00]\x94(\x8c\x07abcdefg\x94h\x01K,e.'
    0: \x80 PROTO      4
    2: \x95 FRAME      19
   11: ]    EMPTY_LIST
   12: \x94 MEMOIZE    (as 0)
   13: (    MARK
   14: \x8c     SHORT_BINUNICODE 'abcdefg'
   23: \x94     MEMOIZE    (as 1)
   24: h        BINGET     1
   26: K        BININT1    44
   28: e        APPENDS    (MARK at 13)
   29: .    STOP
highest protocol among opcodes = 4
