           Summary: Warn for use of array types with va_arg
           Product: clang
           Version: trunk
          Platform: PC
        OS/Version: All
            Status: NEW
          Severity: normal
          Priority: P
         Component: Frontend
        AssignedTo: unassignedclangbugs at nondot.org
        ReportedBy: joerg at NetBSD.org
                CC: llvmbugs at cs.uiuc.edu


Using arrays with va_arg seems to be undefined behavior. It would be useful if
clang actually warned about that, possibly even error by default.

See http://gnats.netbsd.org/45138 for a longer discussion and test cases.
