Vector.push_back(...) read access violation - c++

Question

I don't know why but my program triggers a breakpoint on a line on the first iterations of 2 embedded loops here is the line:
pointerHolder->linkedVertices.push_back(&sphereApproximation.vertices.back());
Here is the section within which this resides (the line is near the bottom):
static const vertice holder[6] = { vertice(0,r,0,0), vertice(r,0,0,0), vertice(0,0,r,0), vertice(0,-r,0,0), vertice(-r,0,0,0), vertice(0,0,-r,0) };
std::vector<vertice> vertices (holder, holder + (sizeof(holder) / sizeof(vertice)));
shape sphereApproximation = shape(0, vertices);
int count;
for (int i = 0; i < 6; i++) {
count = i;
for (int t = 0; t < 5; t++) {
if (count == 5) {
count = 0;
}
else {
count++;
}
if (t != 2) {
sphereApproximation.vertices[i].linkedVertices.push_back(&sphereApproximation.vertices[count]);
}
}
}
bool * newConnection = new bool[pow(sphereApproximation.vertices.size(), 2) - sphereApproximation.vertices.size()]();
vertice * pointerHolder;
for (int i = 0; i < sphereApproximation.vertices.size(); i++) {
for (int t = 0; t < sphereApproximation.vertices[i].linkedVertices.size(); t++) {
if (!newConnection[(i * (sphereApproximation.vertices.size() - 1)) + t]) {
pointerHolder = sphereApproximation.vertices[i].linkedVertices[t];
sphereApproximation.vertices.push_back(newVertice(&sphereApproximation.vertices[i], pointerHolder, accuracyIterator + 1));
for (int q = 0; q < pointerHolder->linkedVertices.size(); q++) {
if (pointerHolder->linkedVertices[q] == &sphereApproximation.vertices[i]) {
pointerHolder->linkedVertices.erase(pointerHolder->linkedVertices.begin() + q);
break;
}
}
sphereApproximation.vertices[i].linkedVertices.erase(sphereApproximation.vertices[i].linkedVertices.begin() + t);
sphereApproximation.vertices[i].linkedVertices.push_back(&sphereApproximation.vertices.back());
std::cout << "gets here" << std::endl;
pointerHolder->linkedVertices.push_back(&sphereApproximation.vertices.back());
std::cout << "does not get here" << std::endl;
sphereApproximation.vertices.back().linkedVertices.push_back(&sphereApproximation.vertices[i]);
sphereApproximation.vertices.back().linkedVertices.push_back(pointerHolder);
}
}
}
I know the declaration for the newVertice(...) subroutine is missing, but I thought it was rather unnecessary, all that needs to be known is that its return type is vertice and it does return a vertice as I have tested. Here are the declerations of the structs I'm using:
struct vertice {
int accuracy;
double x, y, z;
std::vector<vertice*> linkedVertices;
vertice(double x, double y, double z, std::vector<vertice*> linkedVertices) {
this->x = x;
this->y = y;
this->z = z;
this->linkedVertices = linkedVertices;
}
vertice(double x, double y, double z, int accuracy) {
this->x = x;
this->y = y;
this->z = z;
this->accuracy = accuracy;
}
};
struct shape {
double center;
std::vector<vertice> vertices;
shape(double center, std::vector<vertice> vertices) {
this->center = center;
this->vertices = vertices;
}
};
If I've failed to provide anything please drop a comment and I shall amend my question.
