C++ support doesn't work with std::vector

[David Nolden]

For me it works fine! For example in a file like this, I get completion behind 
the "vec[5].", and navigation works for "i":

#include <vector>

class B{int i;};

void test() {
  std::vector<B> vec;
  vec[5].i;
}

Have you tried restarting KDevelop? Sometimes the complex import-structures 
and the updating mess everything up a little(That will be fixed).
