I cannot reproduce this test failure.  I can imagine that the
failure is caused by one or more of the exec() calls in
ext\standard\tests\file\windows_acls\common.inc failing.  For
debugging it might be useful to add an exec() wrapper to that
file:

    function my_exec($cmd) {
        $res = exec($cmd, $output, $status);
        if ($status) {
            echo "FAILED: $cmd\n";
        }
        return $res;
    }

And to replace all exec() calls in common.inc with my_exec().
Could you please check that?

After making those changes (tested on 7.2.23RC1), the output is still the same: 

Testing file with relative path:
Iteration #1: passed.
Iteration #2: passed.
Iteration #3: passed.
Iteration #4: passed.
Testing directory with relative path:
Iteration #1: passed.
Iteration #2: bool(true)

failed.
Iteration #3: bool(true)
bool(false)
failed.
Iteration #4: passed.

While I still have not been able to reproduce this locally, I've
seen this test occasionally failing on AppVeyor (same diff), so
there might be some execution order issue.

Fabien just committed a potential fix[1] for this issue (PHP 7.4).
Can you please check whether this would solve the issue for you?

Re-opening, to not forget about this ticket.  For now, it seems
that Fabien's patch indeed fixed the issue, but lets wait a while
before backporting.

We found that one reason for this test to fail, is when running as
a network service; however, it is already documented that this is
supposed to cause issues[1].

There may be other reasons for this test to fail, but without
further information, or better yet, someone being able to reliably
reproduce the test failure when running under an actual user
account, I don't think that anything can be done here.

So, does anybody else experience bug44859_4.phpt failing?
