Sigsegv error on getline function

Question

I've spent the last couple hours trying to debug this block of code, and I can't for the life of me track down the source of this error.

void readSaveFile() {
int cellIdx = 0;
ifstream myFile;
string nextWord;
string nextLine;
char* tok;
const char* delim = " ,;/\n\t";
char thisLine[30];
myFile.open("VoronoiSave1.txt");
//int idx = 0;
if (!myFile.is_open()) {
    cout << "Unable to open file" << endl;
} else {
    while (!myFile.eof()) {
        getline(myFile, nextLine);
        strcpy(thisLine, nextLine.c_str());
        tok = strtok(thisLine, delim);
        if (tok != 0x0) {
            nextWord = tok;
        } else break;
            if (nextWord == "xBound") {
                tok = strtok(NULL, delim);
                xBound = atof(tok);
                midXBound = xBound /4;
            } else if (nextWord == "yBound") {
                tok = strtok(NULL, delim);
                yBound = atof(tok);
                midYBound = yBound /4;
            } else if(nextWord == "sizeFactor") {
                tok = strtok(NULL, delim);
                sizeFactor = atoi(tok);
            } else if (nextWord == "numberCells") {
                tok = strtok(NULL, delim);
                numberCells = atoi(tok);
            } else if (nextWord == "numberGenerations") {
                tok = strtok(NULL, delim);
                numberGenerations = atoi(tok);
            } else if (nextWord == "displayEvery") {
                tok = strtok(NULL, delim);
                displayEvery = atoi(tok);
            } else if (nextWord == "A0") {
                tok = strtok(NULL, delim);
                A0 = atof(tok);
            } else if (nextWord == "P0") {
                tok = strtok(NULL, delim);
                P0 = atof(tok);
            } else if (nextWord == "conA") {
                tok = strtok(NULL, delim);
                conA = atof(tok);
            } else if (nextWord == "conB") {
                tok = strtok(NULL, delim);
                conB = atof(tok);
            } else if (nextWord == "conC") {
                tok = strtok(NULL, delim);
                conC = atof(tok);
            } else if (nextWord == "conE") {
                tok = strtok(NULL, delim);
                conE = atof(tok);
            } else if (nextWord == "c1") {
                tok = strtok(NULL, delim);
                c1 = atoi(tok);
            } else if (nextWord == "c2") {
                tok = strtok(NULL, delim);
                c2 = atoi(tok);
            } else if (nextWord == "c3") {
                tok = strtok(NULL, delim);
                c3 = atoi(tok);
            } else if (nextWord == "c4") {
                tok = strtok(NULL, delim);
                c4 = atoi(tok);
            } else if (nextWord == "end") {
                tok = NULL;
                break;
            } else if (nextWord == "|"){
                point p;
                tok = strtok(NULL, delim);
                p.x = atof(tok);
                tok = strtok(NULL, delim);
                p.y = atof(tok);
                points.push(p);
                listOfCells[cellIdx].setLocation(p);
                cellIdx++;
            }  
            else tok = NULL;
    //  }
    }
}

myFile.close();
}

This function is supposed to read a txt file line by line and assign values from it into variables for my code. The debugger tells me that it fails on the getline() function somewhere in the middle of reading the file (the same line of the text file each time, and I've checked for any irregularities in that line). I have another function that is similar to this one, with the difference being that it reads smaller files, and it works just fine (they're the same except this one also reads sets of coordinates, too).

Actually, when I try to debug it now to get the specific error, it just gives me a sigtrap error (ntdll!RtlpntMakeTemporaryKey())

This is the text file that it reads:
