In the past I've had the index problem with the Sun Freeware
(including the one automatically installed in /usr/sfw/bin) and
Companion CD 1.13 versions.  I see that Solaris 10 will be coming
with gtar 1.14 in /usr/sfw/bin.  Don't know if that has/will have
problems or not.  IIRC some 1.14's reverted to having problems.

gtar 1.14 is indeed not perfect. See:

http://marc.theaimsgroup.com/?l=amanda-users&m=110354459312987

The backups that 1.14 make are good.  It is when restoring that
tar 1.14 stumbles over any sparse file in the archive.  Using
gtar 1.13.25 on that archive to restore does work however (phew).
There exists a patch for 1.14 to correct this already.

For the record:
plain gtar 1.12 needs to be patched to handle large files (> 2GB).
plain gtar 1.13 makes bad index-lists which amrecover cannot handle,
as does the rarely used 1.13.9x, which changed the index-format again
in an incompatible way.

In production environment I use only 1.13.19 or 1.13.25 currently.
