[Bug-tar] tar bug: "corrupted double-linked list"

[sw_eval]

Hi all!

I recognized a bug in GNU tar on one of our ubuntu system:

When I try to generate a tar archive of /etc and /var/log I have problems with 
the order(sic!) of the two directories.

With 

  tar ... /var/log /etc

it works, but with 

  tar ... /etc /var/log

I get the following error:

*** glibc detected *** /bin/tar: corrupted double-linked list: 0x08088e08 ***
======= Backtrace: =========

This happens only on one(!) machine. All machines are running ubuntu, but 
different versions and 32bit as well as 64bit systems.


Since I have a workaround, I don't need a bug fix. I send this bug report 
mainly to help others who might discover the same bug...

The tar and OS versions are:
