    There is a small bug in your recv program.  In your recvfrom() call the
last argument (&len in your example) is both an input and an output.  It needs
to be initialized to the size of the sin2 argument.  The following change
makes your program work:

*** recv.c      Wed Dec 21 10:31:42 1994
--- recv.c.new  Wed Dec 21 10:30:50 1994
***************
*** 43,48 ****
--- 43,49 ----
  
    while (1)
    {
+     len = sizeof(struct sockaddr);
      n = recvfrom(s, msg, 1300, 0, (struct sockaddr *)&sin2, &len);
      if (n < 0)
        fprintf(stderr, "recvfrom error: %d\n", errno);

    The reason that you got different results compiling it with debug and
without debug is that len was initialized (or actually not initialized) to
different values.  With debug, it must have had a value greater than the size
of a struct sockaddr.
