 Hi,

 It seems that clang expects the libraries for C++ to be at another place:

 {{{
 $ cat foo.cc
 12
 int main()
 {
   return 1 << 34;
 }

 $ clang++-mp-3.9 -fsanitize=undefined foo.cc
 foo.cc:3:12: warning: shift count >= width of type [-Wshift-count-
 overflow]
   return 1 << 34;
            ^  ~~
 1 warning generated.
 $ ./a.out
