Hi Juan,

I've seen that with large sized files (14G in this case) when I use
the "list" option I get wrong uncompressed size and the ratio, of
course, is wrong. I've tested it with versions 1.10 (last just
compiled) and 1.5 (system version).
This is a known limitation, described in the gzip manpage (see the BUGS
section):
The gzip format represents the input size modulo 2^32, so the --list
option reports incorrect uncompressed sizes and compression ratios for
uncompressed files 4 GB and larger.
The documented workaround is to decompress the file and measure its
size:
zcat file.gz | wc -c

Stephen
