c++ - Error with Merge Sort -


i trying create merge sort algorithm in c++ takes vector of generic type input , sorts elements in vector. except getting [run] bus error (core dumped) error everytime try test algorithm.

my code merge sort follows:

template <typename t> void merge_sort(std::vector<t>& vector) { typename std::vector<t>::iterator middle_value = vector.begin()+vector.size()/2;        std::vector<t> left_side(vector.begin(), middle_value);     std::vector<t> right_side(middle_value,vector.end());     merge_sort(left_side);     merge_sort(right_side);     std::vector<t> merged;     int i,j;     while(i<left_side.size() && j<right_side.size())     {     if(left_side.at(i)<right_side.at(j))     {         merged.push_back(left_side.at(i));         i++;     }     else     {         merged.push_back(right_side.at(j));         j++;     }     }     while(i<left_side.size())     {         merged.push_back(left_side.at(i));         i++;     }     while(j<right_side.size())     {         merged.push_back(right_side.at(j));         j++;     }     for(int x=0;x<merged.size();x++)     vector.at(x)=merged.at(x);   }

any light on issue much.
