Hovering over member variables does not show their values

Hovering over a member variable does not show its value when using Midas for RR.

The following example:

class a {
protected:
    int a_1;
};

class b : public a {
    int b_2;
public:
    void foo (int p_3)
    {
        int l_4 = 4;
        a_1 = 1;
        b_2 = 2;
    }
};

int main (int argc, const char *argv[])
{
    class b *r = new b;
    r->foo (3);
}

Setting a break point in foo and hovering over p_3 and l_4 show their respective values. However, hovering over a_1 and b_2 after they have been set does not show their values but instead their types.
