            Bug ID: 33928
           Summary: After r308791 there are numerous est case failures in
                    bootstrap build
           Product: new-bugs
           Version: trunk
          Hardware: PC
                OS: Linux
            Status: NEW
          Severity: enhancement
          Priority: P
         Component: new bugs
          Assignee: unassignedbugs at nondot.org
          Reporter: seurer at linux.vnet.ibm.com
                CC: llvm-bugs at lists.llvm.org

You can see the failures here in the buildbot results:

http://lab.llvm.org:8011/builders/clang-ppc64le-linux-multistage/builds/3289

Failures were occurring earlier but were masked by a compilation problem
introduced by an even earlier revision.
