Error for vector-valued Lagrangian FEs in Github actions with Julia 1.9.x

Documenting here a very annoying error that I have found with vector-valued Lagrangian FEs in Github actions and Julia 1.9.x.

In particular, the following command:

> mpiexec -n 4 --allow-run-as-root --oversubscribe /opt/hostedtoolcache/julia/1.9.1/x64/bin/julia -Cnative -J/opt/hostedtoolcache/julia/1.9.1/x64/lib/julia/sys.so --check-bounds=yes -g1 --color=yes --project=/home/runner/work/GridapP4est.jl/GridapP4est.jl/test/.. /home/runner/work/GridapP4est.jl/GridapP4est.jl/test/mpi/PoissonNonConformingOctreeModelsTests.jl

With the julia script in the status corresponding to, e.g., commit [9fa3996](https://github.com/gridap/GridapP4est.jl/commit/9fa3996115daea7ce6936ed6f25913cc6f779146), crashes (intermittently, not a reproducible BUG, unfortunately), here:

https://github.com/gridap/GridapP4est.jl/blob/9fa3996115daea7ce6936ed6f25913cc6f779146/test/PoissonNonConformingOctreeModelsTests.jl#L152

The error can be found here:

I cannot reproduce the problem in my local machine. When I switch to Julia 1.8 in Github actions the problem seems to disappear.
