If a compressed file consists of several members, the uncompressed size and CRC reported by the --list option applies to the last member only. If you need the uncompressed size for all members, you can use:

Jan 1, 1970 · When using the first two formats, gunzip checks a 32 bit CRC (cyclic redundancy check). For pack , gunzip checks the uncompressed length. The compress format was not designed to allow consistency checks.

Aug 9, 2020 · GNU Gzip is a popular data compression program originally written by Jean-loup Gailly for the GNU project. Mark Adler wrote the decompression part. We developed this program as a replacement for compress because of the Unisys and IBM patents covering the LZW algorithm used by compress.

crc-x86_64 is added as its own package with minimal bindings in crc.c to support, flagged off by the GL_CRC_PCLMUL flag which is only set if the crc-x86_64 package is selected. Tested against gzip with the package included and omitted and gzip builds fine in both case.
