Unfortunately the XRC patches were put into OFED 1.3 before they went
into the upstream libibverbs tree, so I have not reviewed them in
detail.  If XRC support requires an ABI change, then we'll have to
create a new ABI and provide versioned symbols for backwards compatibility.

However your problem seems quite strange: I don't see any change 
to struct ibv_context caused by the XRC patches.  So I don't
understand exactly what is causing the problem you see.  Can you debug
further to see which structure layout change is the real issue?
