Can you send detailed ls output including full time stamps, right after
the above failure, for the following directories:
  top_srcdir
  top_srcdir/libltdl
  builddir/tests/testsuite.dir/086

plus the time at which you ran the test.  Thanks.

FWIW, I've seen issues with some of these tests as well, but they didn't
fail with this particular warning.

Well, but *that* is something that typically happens when your system
clock really was not quite right: after a while, no more files have time
stamps in the future, then everything starts to work.

Not saying that this has to be the case here, but it sure is an
indicator.

Another possibility, yes.
