Ugly code, but a simple fix might be:
int iax_parse_ies(struct iax_ies *ies, unsigned char *data, int datalen) {
struct sockaddr_in moo;
...
case IAX_IE_APPARENT_ADDR:
bcopy(data + 2, &moo, sizeof(moo));
ies->apparent_addr = &moo;
...
Without looking at the actual code, it's hard to say whether this would
actually work (ie. moo is an auto variable, and disappears when the
functions exits, etc).
