man gzip:
BUGS
The gzip format represents the the input size modulo 2^32, so the
--list option reports incorrect uncompressed sizes and compression
ratios for uncompressed files 4 GB and larger. To work around this
problem, you can use the following command to discover a large
uncompressed file's true size:
zcat file.gz | wc -c
The --list option reports sizes as -1 and crc as ffffffff if the
compressed file is on a non seekable media.
In some rare cases, the --best option gives worse compression than
the default compression level (-6). On some highly redundant files,
compress compresses better than gzip.
