CODAN false positive with push_back [message #1063693]

Here is a simple code snippet that triggers a semantic error by codan, while the code still compiles fine (got to turn c++11 on).

#include <vector>

int test() {

    std::vector<int> v1 = {12, 34};
    std::vector<int> v2 = {56, 78};

    //push_back is underlined red.
    v1.push_back(v2[0]);

    return v1[2];

}

The semantic error is: Invalid arguments ' Candidates are: void push_back(const int &) void push_back(int &&) '.

Any way to fix it, or at least make the error disappear from the problem list?

I am having a similar problem with:

std::vector<int> *testVector = new std::vector<int>();
testVector->at(0);

The code compiles fine, but eclipse (CODAN?) is complaining:

Invalid arguments '
Candidates are:
int & at(?)
const int & at(?)
'

There propably is something wrong in my settings, as I had to tweak them a bit to get c++11 to compile at all and to remove 90% of the errors it showed.
