Mixing
C++11 Segmentation Fault with for loop that works previously [on hold]

I'm programming some C++ code to manipulate a PPM formatted image.
I'm a at a point where I get a segmentation fault over a vector<vector<vector<int>>>
This code works to print out the content of Frequency by iterating:
for(size_t i = 0; i < InfoSup.nbL-2; i++){
for(size_t j = 0; j < InfoSup.nbC-2;j++){
for(size_t k = 0; k < Header.ListeSeuils.size()-1; k++){
cout << Frequency[i][j][k] << " ";
}
cout << " ";
}
cout << endl;
}
However, in a another function called like that:
SelectHighest_and_Fill(Displayfrequency(ListeCLF,Header,InfoSup),Header, InfoSup);
Where Select Highest_and_fill is the function in which I get the error, together with Displayfrquency, they are prototyped as such:
vector<vector<vector<int>>> Displayfrequency(vector<vector<int>> ListeCLF,header Header, infoSup InfoSup);
vector<vector<int>> SelectHighest_and_Fill(vector<vector<vector<int>>> Frequency, header Header, infoSup InfoSup);
Now the fun part, the error, I get it in that loop:
int max=0;
int indice_max=0;
int tempVal;
for(size_t i = 0; i < InfoSup.nbL-2; i++){
cout << "I: "<< i << " ";
for(size_t j = 0; j < InfoSup.nbC-2;j++){
cout <<"J: "<< j<< " ";
for(size_t k = 0; k < Header.ListeSeuils.size()-1; k++){
cout << "k "<< k << " ";
tempVal=Frequency[i][j][k];
if (tempVal>max) {
tempVal=max;
indice_max=k;
}
}
}
}
}
Exactly at that piece of code : Frequency[i][j][k]
The IDE then points me to that part of stl_vector.h error
It seems like I'm trying to access data that is not defined, or does not exist, but I iterated over the whole Frequency triple vector with no problem, and iterating it with the exact same loop does not work.
Is there a way to fix this ?
Tank you very much :)

Run this code in debugger and check the size of your Frequency matrix. You are probably out of bounds in at least one of the parameters (i,j,k).
