[New-bugs-announce] [issue39289] crypt.crypt crashes on 3.9 where it didn't on 3.8

[Vinay Sajip]

New submission from Vinay Sajip <vinay_sajip at yahoo.co.uk>:

The following script (cryptest.py):

import crypt

for salt in ('foo', '$2a$04$5BJqKfqMQvV7nS.yUguNcueVirQqDBGaLXSqj.rs.pZPlNR0UX/HK'):
    t = 'test'
    h = crypt.crypt(t, salt)
    print("'%s' with '%s' -> %s" % (t, salt, h))

crashes in 3.9, whereas it doesn't in earlier versions:

$ python2.7 cryptest.py 
'test' with 'foo' -> foy6TgL.HboTE
'test' with '$2a$04$5BJqKfqMQvV7nS.yUguNcueVirQqDBGaLXSqj.rs.pZPlNR0UX/HK' -> None
$ python3.7 cryptest.py 
'test' with 'foo' -> foy6TgL.HboTE
'test' with '$2a$04$5BJqKfqMQvV7nS.yUguNcueVirQqDBGaLXSqj.rs.pZPlNR0UX/HK' -> None
$ python3.8 cryptest.py 
'test' with 'foo' -> foy6TgL.HboTE
'test' with '$2a$04$5BJqKfqMQvV7nS.yUguNcueVirQqDBGaLXSqj.rs.pZPlNR0UX/HK' -> None
$ python3.9 cryptest.py 
'test' with 'foo' -> foy6TgL.HboTE

    return _crypt.crypt(word, salt)
