I re-did the spack environment, and finally it works. Changes include:

  • the custom compilation of OpenMPI and UCX is not specified explicitly as a dependency of fftw and hdf5, because for some reason spack tends to crash that way. It is picked up automatically however, so there is no problem.
  • All compilation is done inside of spack environments. This increases encapsulation a bit and also makes the whole setup a bit faster due to better parallelism. (roughly speaking, spack env depfile && make is the same as spack install but can build unrelated packages simultaneously).

next step for me: put it into the CI in order to be notified swiftly if anything breaks again.
