This doesn't happen on 2.x cPickle, where PUT keys are simply treated as strings.
>>> import pickle, pickletools
>>> s = b'Va\np-1\n.'
>>> pickletools.dis(s)
0: V UNICODE 'a'
3: p PUT -1
7: . STOP
highest protocol among opcodes = 0
>>> pickle.loads(s)
Erreur de segmentation

Same with LONG_BINPUT on a 32-bit build:
>>> s = b'\x80\x03X\x01\x00\x00\x00ar\xff\xff\xff\xff.'
>>> pickletools.dis(s)
0: \x80 PROTO 3
2: X BINUNICODE 'a'
8: r LONG_BINPUT -1
13: . STOP
highest protocol among opcodes = 2
>>> pickle.loads(s)
