Programming :: Packing Sockaddr_storage With Either V4 Or V6 Address?

Running into a weird issue when packing sockaddr_storage with either v4 or v6 address.

To demonstrate the problem, I created a sample test program(limiting it to v4 only addresses). The problem was observed on MAC OS 10.5.8 and Linux RHEL kernel 2.6.9-42 with gcc as the compiler.

* Function packAddrs() runs a for loop packing v4 addresses into a single structure. The input address is same for every iteration, output memory size is adjusted using realloc.

* After successfully packing an address, it prints the packed structure contents using displayPackedAddrs()

* The output is fine for first two iterations. However, at the 3rd iteration, the packed contents seem to have got corrupted. It prints only the first packed address. I have tried using (malloc and memcpy) instead of realloc but no improvement.

Included below is the code and execution output.

#include <stdio.h>
#include <stdlib.h>
#include <string.h>
