This is a bug on my behalf (a bit of too-eager error checking ;-)
Apply the following patch:

diff -r1.36 distribution.c
1315c1315
< if ((port == 0) || (noOfInStreams==0) || (noOfOutStreams == 0) ||
- ---
> if ((noOfInStreams==0) || (noOfOutStreams == 0) ||


It will be applied in the next subrelease, probably also due end of this
week.

Then you will get the semantics as described in the manual, i.e. you
will *not* get 0 as return value, and once sctp_associate is called,
your association will have a port number chosen by the library.
