             Bug #: 13429
           Summary: clang crashes when trying to compile code with lambda
                    function
           Product: clang
           Version: 3.1
          Platform: Macintosh
        OS/Version: MacOS X
            Status: NEW
          Severity: release blocker
          Priority: P
         Component: C++11

for_each(v.begin(), v.end(), [](int a){});
return 0;
}

results in a compiler crash:
