           Summary: Analyser does not understand __attribute__((cleanup))
           Product: clang
           Version: trunk
          Platform: PC
        OS/Version: All
            Status: NEW
          Severity: normal
          Priority: P
         Component: Static Analyzer
        AssignedTo: kremenek at apple.com
        ReportedBy: csdavec at swan.ac.uk
                CC: llvmbugs at cs.uiuc.edu

For exception-safe destruction of Objective-C objects, we use a macro that
declares them using __attribute__((cleanup)) with a cleanup function that sends
a -release message.  This ensures that the object is freed when the function
exits, either normally or via unwinding.  The analyser, however, does not take
the cleanup function into account and so reports a leak for every variable
declared in this way.
