Can't show contents of std::map

I have a map like this:

using namespace std;
map<int, int> m;

m[1] = 1006;
m[2] = 1007;
m[3] = 1008;

When stepping through this, Creator shows the right number of member for this map. But when I try to expand the tree view to see the map's contents, Creator only shows "unavailable synchronous data" and that's it.

cdb handles this nicely.
