Use INT_MAX instead of AF_MAX, since libc might have a smaller value of AF_MAX than the kernel, what causes the test to fail.

What failure are you seeing? It sounds arbitrary to use INT_MAX instead of AF_MAX. I think it is important to understand the failure first.
Please note that AF_MAX is widely used in the kernel.
