BPFile writer aborting on Titan

Created by: pnorbert

$ aprun -n 1 ./heatTransfer_write_adios2 ./heat_bpfile.xml heat.bp 1 1 5 6 1 1 Step 1: Total runtime = 0.00466585s

It segfaults when gathering global metadata. In this example, the subfile is readable, but at larger runs, they are also invalid BP files somehow.
