core dump on CentOS about mana HOT 5 OPEN

I can report that on CentOS 8 the tutorial does not work. it leads to an assertion error during the execution (first execution, not the restart) of the mpi application (getNextAddr: Assertion `0' failed.) Just now tried on CentOS 7 and it works better, however, I am getting an error during the restart: ***@***.*** mana]$ mana_coordinator *** Coordinator/job information written to /home/osboxes/.mana ***@***.*** mana]$ mpirun -np 1 mana_launch contrib/mpi-proxy-split/test/mpi_hello_world.mana.exe & [1] 8035 ***@***.*** mana]$ Hello world from processor test, rank 0 out of 1 processors Will now sleep for 500 seconds ... ***@***.*** mana]$ mana_status --checkpoint ***@***.*** mana]$ Signal received; continuing sleep for 287 seconds. ***@***.*** mana]$ mana_status --quit [1]+ Done mpirun -np 1 mana_launch contrib/mpi-proxy-split/test/mpi_hello_world.mana.exe ***@***.*** mana]$ mana_coordinator *** Coordinator/job information written to /home/osboxes/.mana ***@***.*** mana]$ mpirun -np 1 mana_restart [8146] mtcp_restart.c:799 main: [Rank: 0] Choosing ckpt image: ./ckpt_rank_0/ckpt_mpi_hello_world.mana.exe_2083fef5d9ec709-40000-339712e2b6e.dmtcp [8146] mtcp_restart.c:1458 unmap_memory_areas_and_restore_vdso: ***Error: vdso/vvar order was different during ckpt. /home/osboxes/mana/bin/mana_restart: line 125: 8146 Segmentation fault (core dumped) $dir/dmtcp_restart --mpi --join-coordinator --coord-host $submissionHost --coord-port $submissionPort $options ***@***.*** mana]$ Have you experienced this?
