Autocompletion regression from v2.5

With MSVC10 headers, autocompletion does not work for the situation below. In v2.5.2 it worked.

#include <memory>
struct S {
int a, b, c;
};
namespace test {
// follow symbol under cursor does not work for shared_ptr
using std::shared_ptr;
}
void main() {
// follow symbol under cursor does not work for shared_ptr
test::shared_ptr<S>
p;
p-> // auto-completing after -> does not work
}
