c++ vector push back error

Question

Im getting an error every time I try to debug this with Visual C++ 2008

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

using namespace std;

void load(const char* filename) {
    vector <string*> vec;
    ifstream in(filename);
    char buffer[256];
    while(!in.eof()) {
        in.getline(buffer, 256);
        vec.push_back(new std::string(buffer));
    }
}

int main(int argc, char* args[]) {
    cin.get();
    return 0;
}

get this error

what am I doing wrong?

Answer 1

It looks as though you're building a debug version of your project but you're linking against the non-debug version of the C-Runtime DLL. You can check this in:

[Project] -> Properties -> C/C++ --> Code Generation --> Runtime Library

The runtime library should be listed as: "Multi-threaded Debug DLL (/MDd)" for a debug build.

You should actually find that the project builds just fine as "Release" since CrtDbgReportW is not called by std::vector in release builds and hence doesn't need to find that symbol at link time.
