Comment 0 for bug 1131982

A file gzip'd on VM #1 (Ubuntu 12.04.2 server x64, gzip 1.4-1ubuntu2) will give a CRC error while extracting on VM #2 (Ubuntu 12.04.2 server x64, gzip 1.4-1ubuntu2). Extracting the file on VM #1 works as does extracting the file on Ubuntu 10.04.4LTS. Both VM #1 and VM #2 are running ext4 for their root fs.

I can't upload the original file so I created a random text file by concatenating all linux headers. This file causes the same error:
https://s3.amazonaws.com/gzip-bug/kernel.h.gz

Both files have the same sha512sum:
$ sha512sum kernel.h.gz
0ea4226470f4da8f78b6272d65898c70de193b8a934e94ea81e4e86c8e477e7a44c7f45ef287f12db6eba6073c4726ab9373c883b2595011c9998dc10bff4db5 kernel.h.gz
