Seg vault when linking PISM with YAC v3.4.0
It was reported that when running PISM (Parallel Ice Sheet Model) with YAC, there is a segmentation fault.
In the YAC test-suite test_dummy_coupling5 failed in a trivial MPI-operation in the routine __funlockfile. Which sounds familiar to me and could indicate an issue with either the file system or the MPI implementation. I suggested to first update the MPI implementation to at least openmpi 4.1.2.
Configuration:
- gcc: 11.2.0
- MPI: openmpi 4.0.6
- YAC: v3.4.0
- System: Purdue's Anvil
