segmentation fault in unit-test Field.PeriodicBC

Summary

Segmentation fault in unit-test Field.PeriodicBC on Merlin with the following toolchain:

module load cmake/3.15.5
module load gnuplot/5.2.7
module load Python/3.6.3

module load gcc/8.4.0
module load gsl/2.6
module load OpenBLAS/0.3.10
module load gtest/1.10.0

module load openmpi/3.1.6
module load amrex/18.07_3d
module load boost/1.70.0
module load hdf5/1.10.6
module load parmetis/4.0.3

module load H5hut/2.0.0rc6
module load trilinos/12.18.1

Same problem on macOS and Clang/10 instead of gcc/8.4.0.

But no problem on opalrunner.psi.ch!

Steps to reproduce

Login to one of the login-node of Merlin, compile OPAL with above modules and run unit.tests or run on macOS 10.15 with current Xcode.
