Hi
 
I recently noticed the stats of compressed files larger than 4GB do not report 
correctly.
 
 
Original uncompressed files:
 
-rw-r--r--  1 xxx xxx  1064003197 Aug  1 14:17 file1
-rw-r--r--  1 xxx xxx 12218555103 Aug  1 14:23 file2

 
Files compress fine, but when listing stats from the compressed files:
 
gzip -l *.gz
 
         compressed        uncompressed  ratio uncompressed_name
          370481566          1064003197  65.2% file1
          798651820          3628620511  78.0% file2
 
The uncompressed size is incorrect.
Seems to be 32-bit limit.
 
 
I'm using the 1.3.3 version of gzip.

 

 
Regards 
Rich
