I cannot reproduce the bug with tar 1.27.1 (which I built for Fedora 20 
x86-64).  Can you please give a recipe?  Here's how I tried:

$ echo x | dd of=big obs=1GiB seek=8
0+1 records in
0+1 records out
2 bytes (2 B) copied, 0.000222437 s, 9.0 kB/s
$ ls -l big
-rw-r--r--. 1 eggert eggert 8589934594 Mar 12 10:52 big
$ tar -cf big.tar big
$ tar -tvf big.tar
-rw-r--r-- eggert/eggert 8589934594 2014-03-12 10:52 big
$ mkdir d
$ (cd d && tar -xvf ../big.tar)
big
$ cmp big d/big
$
