title: g++ 4.6.1 compiler error: Error: unknown pseudo-op: `.cfi_personality'
body: <p>I have a file which compiles without errors or warnings on my macbook pro running osx (snow leopard) using g++ (4.6.1). I just uploaded it to our linux cluster (not run by me) and tried to compile there (also using gcc 4.6.1). This time I many strange error messages with the assembler. How do I interpret the following error?</p>
  
  <pre><code>g++ -I../shared/boost_1_47_0 -std=c++0x -O2  -c ../shared/ft.cpp -o ../shared/ft.o
