Re: [Bug-tar] [tar-1.24] summary of test failures

Thanks very much for those tests.  Here's a quick
analysis of them.

I reproduced this problem on Solaris 8.  It is a timing problem
with signals; sometimes it happens, sometimes it doesn't.  I don't
think the choice of compiler matters.  I'll take a look at it.

Someone else has reported a bug about this with OpenBSD
<http://lists.gnu.org/archive/html/bug-tar/2010-10/msg00049.html>.  It
appears to be due to a problem in the way that ksh operates the test
script, and is not a bug in tar.  We are currently trying to figure
out a way to work around the problem by modifying the test script.
Any advice you can provide (please see the thread) would be welcome.

Most likely these are due to the bug discussed in the thread at
<http://lists.gnu.org/archive/html/bug-tar/2010-07/msg00035.html>.
This is on our list of things to fix.  It affects relatively-rare use
cases (getpwd failure).

I independently discovered this bug on Solaris 8, and fixed it after
1.24 came out
<http://lists.gnu.org/archive/html/bug-tar/2010-10/msg00057.html>.

This was also fixed after 1.24 came out, here:
<http://lists.gnu.org/archive/html/bug-tar/2010-10/msg00055.html>.
