globalIndex gather of indirect list (contiguous data) fails

• $FOAM_TUTORIALS/finiteArea/surfactantFoam/planeTransport
  • ./Allrun-parallel and inspect log.makeFaMesh.
  • runParallel makeFaMesh also fails.
• HEAD: 809fc701.
• The case runs with v2112 (HEAD: 14aeaf8d) and in serial mode.
• Traceback:

Write finite area mesh.
