Vtm writer failing with structured data in parallel

The vtk/vtm writer appears to be failing with structured data in parallel. Here is how to replicate:

  • Linux, 5.8.0-RC2, multiple rank - remote server (I'm on 8 ranks).
  • Open Watney's HiFiRE CGNS dataset, sparc-volume.cgns.144.*. Only load Blk-3, Grid (only for load time reduction). I turned all vars on. Apply.
  • File/ Save Data. Vtk Multi Block Files (vtm). I'm calling it deleteMeC. OK, Take defaults, OK.
  • Reset session.
  • Try to open this dataset. I am trying to open the file deleteMeC.vtm. This should open the directory.

Note that this error does not occur if the writer and reader is builtin server. It DOES occur if the writer is parallel, and the reader is builtin.

Error message, which is totally insufficient, is:

ERROR: In /projects/viz/paraview/src/ParaView/5.8.0-RC2/ParaView5/VTK/IO/XML/vtkXMLMultiBlockDataReader.cxx, line 300
vtkXMLMultiBlockDataReader (0xa997bb0): Syntax error in file.
