undefined reference to `__gxx_personality_sj0`

With gcc 4.6 when trying to execute this code:

   #include <iostream>

using namespace std;

#include <bitset>

int main()
{
   //Int<> a;
   long long min = std::numeric_limits<int>::min();
   unsigned long long max = std::numeric_limits<int>::max();
   cout << "min: "<< min << '\n';
   cout << "max: "<< max << '\n';
   cout << (min <= max);
   std::bitset<64> minimal(min);
   cout << "minimal: "<< minimal;

   return 0;
}

I'm getting the following error:
1. undefined reference to __gxx_personality_sj
2. undefined reference to _Unwind_SjLj_Register
3. undefined reference to _Unwind_SjLj_Unregister
4. undefined reference to _Unwind_SjLj_Resume

What on hell is going on?!
