            Bug ID: 88707
           Summary: Random failures of libgomp.c++/task-reduction-(8|10).C
                    on x86_64-apple-darwin18
           Product: gcc
           Version: 9.0
            Status: UNCONFIRMED
          Severity: normal
          Priority: P3
         Component: libgomp
          Assignee: unassigned at gcc dot gnu.org

  Target Milestone: ---
              Host: x86_64-apple-darwin18
            Target: x86_64-apple-darwin18
             Build: x86_64-apple-darwin18

On x86_64-apple-darwin18 I see

WARNING: program timed out.
FAIL: libgomp.c++/task-reduction-10.C execution test
WARNING: program timed out.
FAIL: libgomp.c++/task-reduction-8.C execution test

since they were introduced at revision r265930.

Not only the tests are randomly timed out for -m32 or -m64, but I have to to
kill the executable manually. I don't see the problem on darwin 10.
