hashing (7z h) fails with 'Unknown Error'

[tansy]

I discoverd weird behaviour of hashing command - last master 7z fails with Unknown Error; 7za works. At first I thought it's me as I tried to move mentioned in #141 codecs to Codecs directory but it turned out not to be the case. Also released on 4/04 version 17.04 works fine so it had to be done in between.

Last master:

I'm getting the same error with: 7-Zip [64] 17.04 : Copyright (c) 1999-2021 Igor Pavlov : 2017-08-28 p7zip Version 17.04 (locale=en_US,Utf16=on,HugeFiles=on,64 bits,2 CPUs Intel(R) Core(TM) i5-3470 CPU @ 3.20GHz (306A9),ASM,AES-NI)

Same message: Unknown Error It only affects CRC32, the other hashes are ok. (CRC64, SHA1, SHA256, SHA384, SHA512, XXH32, XXH64, BLAKE2sp, MD2, MD4, MD5)

Roll back to commit 91d7324ff508f28dcb5cb47777fb37b26272aa5d and try again.

[mshedsilegx]

Confirmed fixed by compiling as of commit 91d7324 7z h computes CRC32 correctly.

[mshedsilegx]

d64e1fd is causing the regression. Re-compiling to this commit causes the error above for CRC32.

[jinfeihan57]

OK，I will fix this.
