fixed the issue. Will look into that further If you want to delete pointer element, delete will call object destructor. No need to call List[id]->~Ball() also no need to set pointer to NULL as you are going to erase the element anyway.
code :
std::vector<Ball*> List;

void BallManager::DeleteBall(int id) 
{
    if (id < List.size())   // should check id is still in range
    {  
      delete List[id];
      List.erase(List.begin()+id);
    }
}
  std::vector<std::shared_ptr<Ball> > List;
  void BallManager::DeleteBall(int id) 
  {
     if (id < List.size())   // should check id is still in range
     {  
        List.erase(List.begin()+id);
     }
  }

I wish this helpful for you Three obvious errors:
(1) deleteElement(p) ends up calling free() on a pointer that was not allocated with malloc().
code :
deleteNode(parent);
printf("\nparent node: %d",parent->data);

it should still fix some issue Construct that whomping big object in-place.
Thus, no copying / moving and only minimal stack-usage is neccessary.
code :
for(int x = 0; x < size*size; x++)
    loadedChunkContainers.emplace(std::piecewise_construct,
            make_tuple(x), make_tuple());
How to fix function for deleting element from stack?

I hope this helps . I try to create function that will get some stack with integer numbers and "n" (number for deleting). The function will check the stack and delete the element if find him. The stack need to stay in same order after deleting the "n" element. I try to copy all elements to temporary stack and when find the element not to copy him. After that I want to return all elements to first stack. Something is wrong in my function. I build my function around some code, that I found in the net. , In
code :
    pop(&s, &current);
