C++ function crashes on call ( class constructor )

Question

[ altered ] I had a very strange bug. My debugger used to crash when it calls a function that uses an std::string. I thought this was an error iń my code and at first I didn't realized, that it had to do something with std::strings. Anyway I now know it has to do something with KDevelop, because if I compile this small test file:

#include <iostream>
#include <vector>
#include <string>

int main(int argc, char **argv) {
    std::cout << "Hello, world!" << std::endl;

    std::string test = "test test";
    std::cout << test;
    return 0;
}

It prints "test test" but when I try to debug it, it crashes as well at the call of main() . Anyway, I can debug my project with nemivar, which also uses GDB as backend, with no error.

So this isn't a problem to me anymore and this could be deleted.

In your search_str_in_vector() function you dereference an end() iterator which is not allowed and results in undefined behaviour. Your for loop is also one element larger than the vector (start from vector.size()-1 instead).
