Mark,
I saw your configuration has hypre. If you could run with master, you may try -matptap_via hypre.
This is worth trying. Does this even work with GAMG? Treb: try hypre anyway. It has its own RAP code.
It uses BoomerAMGBuildCoarseOperator directly with the AIJ matrices.

Mark: Try '-matmatmult_via scalable' first. If this works, should we set it as default?
If it is robust I would say yes unless it is noticeably slower (say >20%) small scale problems.
