            Bug ID: 63291
           Summary: ASan reports stack-buffer-overflow in some cilkplus
                    tests.
           Product: gcc
           Version: 5.0
            Status: UNCONFIRMED
          Severity: normal

         Component: testsuite
          Assignee: unassigned at gcc dot gnu.org
          Reporter: chefmax at gcc dot gnu.org
              Host: x86_64-pc-linux-gnu
            Target: x86_64-pc-linux-gnu

These tests failed with stack-buffer-overflow if run with ASan enabled:
