    <p>Hei,</p>
    <p>I just encountered an issue which I can not solve on my own. I
      wrote a test program on my development machine, and compilation
      works fine, but when trying to compile it on the production
      machine compilation fails with</p>

    <p>Where does that error come from, and how can I fix it/circumvent
      it? I compile the program using gcc 8.2.0 (including mpi-wrappers)
      on the production machine, and with gcc 9.3.1 on the dev machine.</p>
    <p>Thanks,</p>
