Comment 9 for bug 1713434

Weird. I managed to run the test on a POWER9 box today, too, and it works for me:

TEST: tests/prom-env-test... (pid=18912)
  /ppc64/prom-env/mac99: OK
  /ppc64/prom-env/g3beige: OK
  /ppc64/prom-env/pseries: OK
PASS: tests/prom-env-test

Which OS and C compiler are you using?

Also, could you please try to add this patch (to add "-serial /dev/stderr") and then post the console output of the prom-env-test:
