            Bug ID: 31068
           Summary: testsuite hard_link_count_test_suite failing on btrfs
                    fs.
           Product: libc++
           Version: 3.9
          Hardware: PC
                OS: Linux
            Status: NEW
          Severity: normal
          Priority: P
         Component: All Bugs
          Assignee: unassignedclangbugs at nondot.org

    Classification: Unclassified

While building llvm 3.9.0 and libc++ on buildhost with btrfs filesystem libc++
tesuite fails. On ext3 fs works without any observable problems.
