[Bug-tar] [tar] tar-1.22 build feedback

[Nelson H. F. Beebe]

I now have completed 51 test builds of tar-1.22 on about 20 flavors of
Unix in my test lab.  

While about half of them have been successful, and are now installed
here, there are some test failures that are repeated across platforms,
making me suspect an error in the tests themselves.

Here is a compact summary of the test failure reports, in ascending
order of test numbers, prefixed with the frequency of occurrence in
the logs:

% grep -h FAIL *.log | sort | uniq -c
  1   2: decompressing from stdin                        FAILED (pipe.at:33)
  6  22: extracting selected members from pax            FAILED (extrac05.at:38)
  1  23: mode of extracted directories                   FAILED (extrac06.at:36)
  1  26: incremental                                     FAILED 
(incremental.at:26)
  1  27: restore broken symlinks from incremental        FAILED (incr01.at:30)
  4  30: working --listed                                FAILED (listed02.at:31)
  1  31: renamed files in incrementals                   FAILED (incr03.at:31)
  1  32: proper icontents initialization                 FAILED (incr04.at:34)
  3  33: renamed dirs in incrementals                    FAILED (rename01.at:27)
  3  34: move between hierarchies                        FAILED (rename02.at:27)
  3  35: cyclic renames                                  FAILED (rename03.at:26)
  1  36: renamed directory containing subdirectories     FAILED (rename04.at:30)
  2  37: renamed subdirectories                          FAILED (rename05.at:27)
  1  40: link count gt 2                                 FAILED (link01.at:36)
  1  46: multivolume dumps from pipes                    FAILED (multiv01.at:30)
  1  49: split directory members in a MV archive         FAILED (multiv04.at:39)
 10  67: compressed format recognition                   FAILED (comprec.at:25)
  1  70: truncate                                        FAILED (truncate.at:32)

In each case, I have refrained from installing the newly-built tar.

Notice test #67: I see that failure on GNU/Linux (Alpha and IA-32),
FreeBSD 6 (IA-32), Mac OS X (PowerPC and IA-32/EM64T/AMD64), NetBSD
(IA-32), and Solaris x86.

Test #22 fails only on Mac OS X (PowerPC and IA-32/EM64T/AMD64).

Test #30 fails on Mac OS X (PowerPC only), OSF/1 Alpha, Solaris (only
IA-32, not AMD64).

Tests #33--37 fail on FreeBSD 6, Mac OS X (PowerPC only), and  OSF/1
Alpha.

I can provide build logs on request, but perhaps reports from others
will show whether my test failures are common and widespread.

On some platforms, I can do additional builds with several other
compilers (nvcc, opencc, pathcc, pgcc, suncc, ...), to weed out
possible compiler code-generation errors that might be responsible for
test failures.
