Утечка памяти при выполнении функции над массивом

Question

Здравствуйте, мне понадобится помощь при следующем утечке кода и памяти.

Журнал ошибок из этой программы показывает I`m encountring следующей утечки в моей программе:

Учитывая мою функцию и Repository класса были ли я сделать что-то неправильно ...

Класс Header (полное):

#ifndef ASSIGNMENTREPOSITORY_H_ 
#define ASSIGNMENTREPOSITORY_H_ 

#include "Assignment.h" 
#include <vector> 

class AssignmentRepository{ 
private: 
    vector <Assignment> assignments; 
public: 
    vector <Assignment> getAll(); 
    void save(Assignment); 
    void delByID(int); 
    void editAssignment(Assignment); 
    int searchById(int); 
    void printAllAssignments(); 
    Assignment *getAssignment(int i); 

    ~AssignmentRepository(); 
}; 

#endif /* ASSIGNMENTREPOSITORY_H_ 

Класс СРР (часть):

int AssignmentRepository::searchById(int a){ 
for(unsigned i=0; i<assignments.size(); i++){ 
    if(a == assignments[i].getID()){ 
     return i; 
    } 
} 
return 0; 
} 

void AssignmentRepository::delByID(int i){ 
int check; 
check = searchById(i); 

if(check != 0){ 
    assignments.erase(assignments.begin()+check); 
} 
else{ 
    throw RepoException("ID does not exist in the database!"); 
} 
} 

Answer 1

Theres некоторое исключение в этой функции delByID() или это removeAssignment()
