Hi, after having the build succeed but tests fail on an IBM POWER8 system
(RHEL 7.1, gcc 4.8.3,
hdf5-1.8.17), I turned to this (https://github.com/HDFGroup/build_hdf5)
repository's Blue Gene
build scripts, reasoning that the architecture (OpenPOWER) would be
compatible. The test results
differ (overflow tests are skipped), but it still ultimately fails.

Are these test failures related to my architecture/setup, or are they a
known issue?
