Does -l option of gzip work correctly for large files (about 10GB)?

[Peng Yu]

Hi,

$ gzip -l 28122s_2_sorted.txt.gz
         compressed        uncompressed  ratio uncompressed_name
         1247648790          1285935835   3.0% 28122s_2_sorted.txt

The uncompressed file size according to "gzip -l" is about 1.2GB.
However, I extracted the file. The file size is 9.2GB. I'm wondering
if there is a bug in gzip when it deals with large files.

$ ls -hltr 28122s_2_sorted.txt
-rw-r--r-- 1 nobody nogroup 9.2G 2011-07-12 15:39 28122s_2_sorted.txt

$ gzip --version
gzip 1.3.12
