解决方式如下：

    wget http://llvm.org/releases/3.3/llvm-3.3.src.tar.gz
    tar xvzf llvm-3.2.src.tar.gz
    cd llvm-3.2.src/tools
    svn co llvm-project - Revision 214475: /cfe/tags/RELEASE_33/final clang
    cd ../projects
    svn co llvm-project - Revision 214475: /compiler-rt/tags/RELEASE_33/final compiler-rt
    cd ..
    ./configure --with-pic
    make -j4 REQUIRES_RTTI=1
    sudo make install

I forget this option  (REQUIRES_RTTI=1)  causes the problem.
