Now that you have finally shown us the output from the first part of my code, it is obvious that something is overwriting the roll_num member of struct student (after the first element in the linked list) with a pointer. If you convert the bad values in roll_num from decimal to hexadecimal you'll note that the value is between the values of the pointers assigned to temp->name and temp->next.
For example 24736352(decimal) == 1797260(hex) and the pointer assigned to head is 17297250(hex) and the pointer assigned to head->name is 1797270(hex).
This should make absolutely no difference, but please try changing:
to:
Assuming that doesn't make any difference, while you're exploring gdb watch what gets assigned to temp->roll_num.
