I'm getting strange behavior using datatypes in a one-sided
The attached example performs an accumulate into a patch of a shared 2d
matrix. It uses indexed datatypes and can be built with displacement
or absolute indices (hindexed) - both cases fail. I'm seeing data
validation errors, hanging, or other erroneous behavior under OpenMPI
