sort of structure in c language

hello friend,   
     I encountered a problem: memory error occurred sorting structure.


My code is as follows:


void bubble_sort(struct Student *h) // On the "Total" to sort.
{
struct Student *temp=h,*p;
    int swapped;
    int T_stu_id;
char T_name[15];
float T_score[CURRICULUM_MAX];
float T_Average;
float T_Total;
/*
if(h!=NULL){
       do 
{
swapped=0;
temp=h;
for (;temp->next!=NULL;)
{
  p=temp->next;
  if(temp->Total>p->Total){
   T_stu_id=temp->stu_id;
strcpy(T_name,temp->name);
T_score[CURRICULUM_MAX]=temp->score[CURRICULUM_MAX];
T_Average=temp->Average;
T_Total=temp->Total;


temp->stu_id=p->stu_id;
strcpy(temp->name,p->name);
temp->score[CURRICULUM_MAX]=p->score[CURRICULUM_MAX];
temp->Average=p->Average;
temp->Total=p->Total;


p->stu_id=T_stu_id;
strcpy(p->name,T_name);
p->score[CURRICULUM_MAX]=T_score[CURRICULUM_MAX];
p->Average=T_Average;
p->Total=T_Total;


swapped=1;
 }
  temp=temp->next;
 
}
} while (swapped);
}
print(h);
*/


}

I do not want to use the above algorithm, because it will change the original position.
Note: Do not exchange element, they only change the pointer field.
Annex has my complete code.


Thank very much.  :)
