Hi,
    I have a question that maybe a bug or not.

We ship a product that installs using gzip. the product name is
IBM_DataReplDash_11.3.3.0_Linux_x86.bin.
Our build machine that build our product is linux enterprise red hat 6.6
sentiago which includes gzip 1.3.12 (output of gzip -V is 1.3.12).

We have a customer who installed our product and has the version gzip 1.3.3
and who gets the following error even though the download
was done in binary format.

Problem Description/Reason for Collaboration:
When customer tried to install latest dashboard using
IBM_DataReplDash_11.3.3.0_Linux_x86.bin, he gets the following
error:
Preparing to
install...
Extracting the JRE from the installer
archive...
Unpacking the
JRE...
gzip: /tmp/install.dir.24732/Linux/resource/vm.tar.Z:
invalid
compressed data--crc
error /tmp/install.dir.24732/Linux/resource/vm.tar.
Z: not in compressed format
gzip: /tmp/install.dir.
24732/Linux/resource/vm.tar.Z: invalid compressed data--crc error
The
included VM could not be uncompressed (GZIP/UNCOMPRESS). Please try
to
download the installer again and make sure that you download
using
'binary' mode. Please do not attempt to install this
currently
downloaded copy

File permission bits is set to
777 for IBM_DataReplDash_11.3.3.0_Linux_x86.bin

Someone in test downloaded and installed successfully on his
Linux which was the exact version as the customer.  We compared
his
CHECKSUM on the ftp'ed copy to the successful implementation
in
test.  They were
identical.

In viewing the error information and traces,the tester noted the
following:

linux is Redhat 6.7
Santiago.
Customer's gzip version is:   gzip  -V  gzip
1.3.3  (2002-03-08)                                                                   

The successful test from the test has a gzip version of
gzip -V   gzip
1.3.12

Not finding any other differences, we wondered if that back-level
of
gzip would cause the problem????!

Thanks in advance for your response.. our customer is asking
us so we'll appreciate any input..

Thanks,
