Hi, I might need more information about the crc32c package you used. I can't reproduce with crc32c==2.2

Hi @lanpa

pip list | grep 'crc32c'
crc32c                             2.2
google-crc32c                      0.1.0

[lanpa]

I can reproduce with google-crc32c==0.1.0. After update to google-crc32c==1.1.2, the error is gone.

Thanks @lanpa, with google-crc32c==1.1.2, it works now.
