The call gethostbyaddr returns a pointer to a static hostent structure that will be overwritten by subsequent calls. Setting hostname equal to the return value of gethostbyaddr will modifiy the value of hostname to point away from the memory you allocated; thus you get a memory leak. Use memcpy to save the contents of the return value to the local struct if required.
