I am debugging stack with defined  SOCKET_DEBUG.
In line 761-762 occur null pointer exception.

>  if (*fromlen > saddr.sa.sa_len) {
>          *fromlen = saddr.sa.sa_len;

The reason is line 739:

>#if !SOCKETS_DEBUG
>      if (from && fromlen)
>#endif /* !SOCKETS_DEBUG */


Maybe add line

>  if (from && fromlen)

before lines:

>  if (*fromlen > saddr.sa.sa_len) {
>          *fromlen = saddr.sa.sa_len;
>  }
>  MEMCPY(from, &saddr, *fromlen);
