I missed the following lines when I did cut and paste of the code -
elem -> u.txwr.opcode = IB_WR_SEND;
elem -> u.txwr.next = NULL; /* Send only one */
So it is not the obvious error, it may be something else.
(Yes, I need to correct the coding style errors.)

It's a little hard to debug without being able to run your code and
reproduce the error. The only things I see obviously wrong are that
you never seem to set elem -> u.txwr.opcode to IB_WR_SEND, so you may
be posting an invalid work request, and also you never set elem ->
u.txwr.next to NULL, so ib_post_send() could follow the next pointer
into some other memory and post a random work request.
(BTW, if your coding style is to put spaces around every operator,
shouldn't you write things like 'elem -> u . txwr . next'? ;)
