I might have missed that earlier or this may be just some sort
of insignificant/misleading clue:

but do you indeed compile corosync using x32 ABI?  (moreover
while pristine x86_64 libqb is used, i.e., using 64bit pointers?)

Perhaps would be good to state any such major divergencies if
so unless I missed that.
