Inserting a pair into multimap on osx

Question

I need some help! I'm using a multimap to map the indices of musical notes, so I can access them by a string name of the note, as well as the int value. However, the code works perfectly fine on Windows, but when moving it to OSX (the latest version). I get a "Thread 1: EXC_BAD_ACCESS (code=1, address=0x0)" error anytime insert is used.

Runtime Error

I know I'm not using best method to insert the notes and indices into the multimap, but I intend to rewrite it.

I've tried several method to get it working, but no success. Here the code.

Header

class zelmNote
{
private:
    static bool bNoteMapped;
    static multimap<int, string> noteToName;
    static multimap<string, int> nameToNote;

    static void mapNotes();

public:
    zelmNote();
};

multimap<string, int> zelmNote::nameToNote;

    string noteName = "";

    noteToInt.insert(pair<string, int>("G#", 8));
    intToNote.insert(pair<int, string>(8, "Ab"));
    noteToInt.insert(pair<string, int>("G#", 8));*/
    //Do natural notes
    for (char c = 'A'; c <= 'G'; c++)
    {
        noteName = ofToString(c);
        noteToName.insert(pair<int, string>(i, noteName));
        nameToNote.insert(pair<string, int>(noteName, i));
        if (i == 11)
        {
            i = 0;
        }
        else if (i == 4)
        {
            i++;
        }
        else if ((i != 11) || (i != 4))
