Package: emacs
Severity: minor
Version: 26.0.90

Current emacs-26 branch on RHEL 7.4, using -lglibc (inotify).
I've several times had the following odd-looking failure of
file-notify-test03-events during "make -j8 check".
Resembles https://debbugs.gnu.org/26126 ?

No.

An unexpected event on unrelated file "/tmp/signed-bad.elcBJAl1B"
happened while watching directory "/tmp".

I've fixed this by adding an own subdirectory below "/tmp", which will
be watched for the test. Committed to the emacs-26 branch, because only
a test file is changed.

If the problem happens again, pls reopen the bug.

Best regards, Michael.
