Are attributes supported with SST + FFS?

Created by: keichi

The heat transfer example in adiosvm/Tutorial/heat2d/cpp/ terminates with the following error when using SST engine and FFS marshaling:

gndx       = 100
gndy       = 100
rank 0 reads 2D slice 100 x 100 from offset (0,0)
ERROR: found null pointer in call to Attribute<T>::Data()

Usage: heatAnalysis  input  output N  M
  input:   name of input data file/stream
  output:  name of output data file/stream
  N:       number of processes in X dimension
  M:       number of processes in Y dimension

It seems that InquireAttribute() is returning an empty attribute object.

Since the same workflow works with SST + BP, InSituMPI and BPFile, I think it is a problem with FFS marshaling.
