[Bug-tar] Small bug in tar-1.29

[Rob Gross]

Hi,

This report is for tar-1.29, compiled and installed on Mac El Capitan.
When the environment variable "LANG" is not set, tar cannot handle a
compressed archive--the error is "broken pipe".  For example:

    m3rgma0371carn - T tar tvzf archive.tgz
    gnutar: Child died with signal 11
    gnutar: Error is not recoverable: exiting now
    m3rgma0371carn - T $ export LANG=" "
    m3rgma0371carn - T $ tar tvzf archive.tgz
    drwxr-xr-x gross/staff       0 2016-08-29 12:10 hsperfdata_gross/
    drwx------ gross/staff       0 2016-08-13 14:41 
com.apple.AddressBook.ContactsAccountsService/
    [...]

There is no problem if I gunzip the archive first, and then run tar.

The broken pipe happens whether tar is compiled with clang or gcc-6.1.
I think that this only happens when gettext, libiconv, and libintl are
all installed.  I don't know if there are other libraries as well that
are involved in replicating the error.

I'm happy to send you config.log, if you need that to decipher the
problem.  I much prefer using gnutar to bsdtar, which is the Mac
default, and I spent a lot of time trying to understand the reason for
the error.

Thanks.  Let me know if you need more information.--Rob
