User-Agent: Mozilla/5.0 (X11; U; Linux i686; en-US; rv:1.7.12) Gecko/20050922 Fedora/1.0.7-1.1.fc4 Firefox/1.0.7

Description of problem:
unzip fails for large files in zip archive with message:
"error:  invalid compressed data to inflate"

Version-Release number of selected component (if applicable):

How reproducible:

Steps to Reproduce:
1. Add 2 files (one 3GB bb, one <1MB cc) to zip: "zip a.zip bb cc" unzip -v a.zip
Archive:  a.zip
 Length   Method    Size  Ratio   Date   Time   CRC-32    Name ("^" ==> case
--------  ------  ------- -----   ----   ----   ------    ----   conversion)
3227215839  Defl:N 3211820154   1%  02-02-06 20:19  93adbffd  bb
     295  Defl:N      195  34%  01-19-06 19:53  762a3a49  cc

3227216134         3211820349   1%                            2 files

2. Test: "unzip -t a.zip" gives "error:  invalid compressed data to inflate"
3. unzip a.zip fails: file bb has size zero.

Actual Results:  Extraction of large file in archive fails (size zero)

Expected Results:  Extraction of all files in archive ok.

Comment 1 Ivana Varekova 2006-02-09 08:38:57 EST
This bug is fixed in the last upstream version of unzip (UnZip 6.00c) so the
next stable upstream version will not contain this problem.
