Program received signal SIGSEGV, Segmentation fault

Ok... I am ripping my hair out... Why am I getting segmentation fauls when I am passing a string called "name" with contents "joel" into

void person::setName(string newName)
{
    personName = newName;
}

Header file:

class person {
public:
    int getID();
    string getName();

    void setID(int newID);
    void setName(string newName);
private:
    int personID;
    string personName;

};

btw... the function call is by a child, although I dont see how that could cause an issue.
