Problem description:
While working on stack implement I have been facing problem " signal: illegal instruction(core dumped) " on console continuously and I think it may be because of arrow operator (->) is not working properly as I am facing this problem only when access member of stack using pointer.
so, In the end I want to know is this really a bug or some different problem .

you’re using the s variable before giving it a value, which is undefined behaviour. Try doing this instead:

struct stack s = {.size = 80, .top = -1};
s.arr = (int *)malloc(s.size * sizeof(int));
