            Bug ID: 24136
           Summary: Regression(r242293:242298): clang very crashy
           Product: clang
           Version: trunk
          Hardware: PC
                OS: All

          Severity: normal
          Priority: P
         Component: Frontend
          Assignee: unassignedclangbugs at nondot.org

Clang started crashing very early during a chromium build on linux, mac,
windows. Probably crashes when building anything interesting.
