Re: [Bug-tar] [GNU tar 1.26] testsuite: 39 failed

Paul,

Thanks for the quick reply.

I hacked the testcases script to extract test39, removed the test framework stuff, added test case separators and ran it with -x as requested.  The log is attached below.

I installed the binary in /usr/local/bin despite the test failure to ensure that the test script picked up the gnu tar rather than the default AIX one.

Let me know if you require anything else.

I've had a quick look at the test scenario, but cannot see any obvious reason.

Can you reproduce the problem with just the shell script
that failed?  If so, can you run it with 'sh -x' so
that we know which 'diff' command produced output?
