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
Traceback (most recent call last):
File "/home/vinay/projects/scratch/cpython/cryptest.py", line 5, in <module>
h = crypt.crypt(t, salt)

I fail to reproduce the issue on the master branch of Python on Fedora 31. |

I can also reproduce it on Ubuntu 16.04.6 LTS (the first Ubuntu was the Linux Mint version based on Ubuntu 18.04). |

Another data point: both failing machines were VMware virtual machines. |

It appears that a check for the return value from the crypt/crypt_r primitives was added to fix bpo-38402. So, this is expected behaviour in Python 3.9. Change was in https://github.com/python/cpython/commit/0d3fe8ae4961bf551e7d5e42559e2ede1a08fd7c |
