           Summary: -Wmissing-noreturn produces a false positive on some
                    constructors
           Product: clang
           Version: trunk
          Platform: PC
        OS/Version: All
            Status: NEW
          Severity: normal
          Priority: P
         Component: C++
        AssignedTo: unassignedclangbugs at nondot.org

Test case

If you compile the attched file:
    struct Wiffle {
        Wiffle(void* woffle)
            : m_woffle(woffle)
        {
        }
    private:
        void* m_woffle;
    };

with
clang++ -c -Wmissing-noreturn foo.cpp

You get an erroneous warning:

foo.cpp:4:9: warning: function could be attribute 'noreturn'
[-Wmissing-noreturn]
        {

This of course breaks those projects using -Werror :D
