I am using Julia v1.9.3 on macOS (ARM architecture). I cloned T8code.jl, activated the examples folder as project with T8code.jl and MPI.jl as dependencies:
(examples) pkg> st
Status `~/.julia/dev/T8code/examples/Project.toml`
[da04e1cc] MPI v0.20.15
[d0cc0030] T8code v0.4.1 `..`
The examples step0 to step4 run without problems. However, julia --project=. t8_step4_partition_balance_ghost.jl crashes with the following message
[t8] [step5]
[t8] [step5] Hello, this is the step5 example of t8code.
