           Summary: Missing -analyzer-check-objc-missing-dealloc also
                    skips leaked ivars
           Product: clang
           Version: unspecified
          Platform: Macintosh
        OS/Version: MacOS X
            Status: NEW
          Severity: normal
          Priority: P
         Component: Static Analyzer
        AssignedTo: kremenek at apple.com
        ReportedBy: kevin at sb.org
                CC: llvmbugs at cs.uiuc.edu

When scan-build is run without the -analyzer-check-objc-missing-dealloc flag,
the static analyzer also fails to report ivars that should have been released
in -dealloc and were not. My expectation of this flag is that it only warns me
when I'm missing the -dealloc method in its entirety, but has no effect on
warning me when I fail to release an ivar in -dealloc. In practice, the lack of
this flag seems to make the static analyzer completely ignore the -dealloc
method and therefore fail to warn me when I'm leaking an ivar.
