           Summary: scan-build failures on bind 9.9.0
           Product: clang
           Version: trunk
          Platform: PC
        OS/Version: Linux
            Status: NEW
          Severity: normal
          Priority: P
         Component: Static Analyzer
        AssignedTo: kremenek at apple.com

    Classification: Unclassified


When im running scan-build on bind 9.9.0 (using clang 3.2 trunk 156903), and
get a lot of the type of errors listed below.

Because there are a lot of these failures and it might just turn out to be the
same issue for all, im a bit reluctant to add them all to this bug report. But
the entire generated report inlcusing failures, preprocessed files etc. can be
found here :
