python libclang incorrect parsing of vector in class

[d-e-e-p]

Parsing the following code with Python libclang:

#include <map>
#include <vector>

struct Map {
  // m_visible shows up in python libclang AST
  std::map<int, int> m_visible;
  // m_invisible is missing in python libclang AST
  std::map<int, std::vector<int>> m_invisible;
}; 

main(){
  Map m;
  return 0;
}

m_visible shows up but m_invisible doesn't show up in AST.
