[Bug c++/35686] New: Incorrect value returned by function that uses a std::vector

["lmdv_gnu at mandata dot nl" <gcc-bugzilla at gcc dot gnu dot org>]

Very simple function returns value of vector-item instead of the correct value.
Code compiles without any problem. Running it returns incorrect value. 
Tried it with Intel and Microsoft compilers, both return the correct value.

Code (since I do not see a method to attach anything here...):

#include <iostream>
#include <vector>

std::vector<int>  next;
long numOfNodes = 5;

int addNode(void)
{
    next.push_back(-1);
    return numOfNodes;
}

int main ( int argc, char *argv[] )
{
    next = std::vector<int> ();
    next.push_back(-1);

    next[0] = addNode();

    std::cout << "Returned value:" << next[0] << std::endl;
    std::cout << "Real Value:" << (numOfNodes) << std::endl;
    return 0;
}
