This bug should have been fixed a few days ago.. I suspect when you
tested you probably didn't have this commit:

rxe: Fix dropped padding in rxe_queue
Dropping it was a typo.

However, this assertion is only present in an even newer checkin.
But, it can only trigger if a slightly older, mismatched, provider
library is present.
So, I think, your environment is messed up with mismatched
libaries and providers..
Manually copying files into /usr/ surely contributed to this,
cmake pre-install output has embedded rpath's and cannot be placed in
/usr/

The trouble with the default 'make install' is that it puts everything
in /usr/local, so it doesn't actually replace your existing local
install and unexpected stuff can happen if the two overlap improperly.
You don't need to install it to test it. Just use ./build.sh and run
the binaries or LD_LIBRARY_PATH the libraries under build/lib/. This
is designed to work properly without interfering with the system
install.
When you want to install it I always recommend making packages, the
redhat/rdma-core.spec will build proper RPMs for el7 that will cleanly
upgrade your existing ones without leaving conflicting residual stuff
around.
Most likely at this point you need to wipe out everything you have
done to /usr and /usr/local and start again.
