Eclipse CDT Kepler does not allow "Display as array..."

I am trying to debug a C++ program using Eclipse CDT:

#include <vector>
using namespace std;

int main() {
  vector<int> test (4,100);
  return 0;
}

(*((test)+0)@4) Error: Multiple errors reported.\ Failed to execute MI command: -var-create - * (*((test)+0)@4) Error message from debugger back end: No symbol "operator+" in current context.\ Unable to create variable object

How can I view the values of my arrays while debugging?

I am using:

Dive a bit deeper into the structure of the std::vector variable, and look for s.th. named _M_start or alike (may be implementation dependent).
Cast this one to the final type array you know and want to see.

The reason is, that std::vector<T> just wraps and manages an array of T internally and thus can't be displayed as an array itself.
