[FLASH-USERS] Guard-cell fill problem / memory trampling on BG/P

Hi FLASH users,

I'm running into a problem on the Argonne BlueGene/P "Intrepid" in which 
it appears that the guard cell filling operation is failing to fill in 
appropriate values. I'm getting a bunch of zeros on the edges in 
density, energy, and internal energy, which then triggers a failure in 
the EoS. I'm using the latest release FLASH3.3. Setup command:

./setup <Sim> -3d -auto +cube16 +cartesian +parallelio +pm4dev 
-objdir=obj_SNIa_convect_F3.3 -maxblocks=45 
-with-unit=Particles/ParticlesMain

The modifications that I have made do not overwrite these quantities in 
the solution data. Has anyone else run into this kind of problem?
I've attached the standard output from the run with " [EOS Helmholtz] 
WARNING!  Mask setting does not speed up Eos Helmholtz calls" removed.

Any help or experiences would be greatly appreciated.
Thanks,
-Aaron
