[Bug-tar] SIGPIPE problem and regression for tar 1.21 on Interix

[Martin Koeppe]

Hi,

I'm using GNU tar on Interix. See http://www.debian-interix.net/
for more details.

I have 2 problems (maybe related) with tar:

1. I encountered some .tar.gz files which I cannot extract correctly.
Most others work well. One of those failing files is:
http://ftp.de.debian.org/debian/pool/main/s/smstools/smstools_3.1.orig.tar.gz

I get:

   $ tar --version
   tar (GNU tar) 1.20

   $ tar xzf smstools_3.1.orig.tar.gz
   tar: Child died with signal 13
   tar: Error exit delayed from previous errors

The archive gets extracted anyway, but tar fails. These ones both 
work, however:

   $ gzip -d -c smstools_3.1.orig.tar.gz | tar xf -
   $ cat smstools_3.1.orig.tar.gz | tar xzf -

I then tried some old versions of tar. 1.16.1 is also failing, but 
1.15.9 does not fail on that archive.


2. I then tried building tar 1.21, and I encountered that the tests 
don't go through anymore (3 failed), while they did for 1.16.1 and 1.20.
  2: decompressing from stdin                        FAILED (pipe.at:33)
 22: extracting selected members from pax            FAILED (extrac05.at:38)
 56: short records                                   FAILED (shortrec.at:28)
I have attached the testsuite.log for both 1.20 and 1.21.

You can also find the build log for 1.20 at
http://www.debian-interix.net/debian-interix/pool/unreleased35/main/t/tar/tar_1.20-1+interix.1_20081210-2150.gz

I can provide more info or do some tests on request.


Many thanks in advance

Martin
