Can someone tell me why this simple tcp program crashes aix 4.1.4 .
I run this program as a normal user, and the second connect crashes aix.
is it just connect's old bug from aix ? i have tried it in aix 3.2
but it works only in 4.1.4.

server.sin_family = AF_INET;
server.sin_port = 23;
connect(sock, (struct sockaddr *)&server, sizeof server);
shutdown(sock, 2);
server.sin_port = 24;
connect(sock, (struct sockaddr *)&server, sizeof server);
