Hi Lawrence,
I just rebuilt PETSc with the debugging=1 option, and indeed It get a more verbose error message, see below. It crashes somewhere in HYPRE_SetupXXX.
Still, that only tells me that something is going wrong in the hypre setup AMG routine.
Yep, so I'm not sure what the problem is, I wonder if it's worthwhile reporting to the hypre team.
Cheers,
Eike

So this is calling HYPRE_BoomerAMGSetup, which is a hypre call. So I'm again not sure what's going wrong, but something inside hypre again I guess.
