Transient failure in ExampleAdvancedPSDMads test

After adding set -o pipefail after the hash-bang line in the runExampleTest.sh script (in order to detect failing library tests — see https://github.com/bbopt/nomad4dev/issues/707), the ExampleAdvancedPSDMads test fails, but seemingly only sometimes. Here is the relevant section of the log of my latest (failed) build (through Guix) of NOMAD:

This issue is a duplicate of https://github.com/bbopt/nomad4dev/issues/711. I've created it in order to have a public issue to reference in the comments of the Guix package for NOMAD (which disables this particular test). See https://issues.guix.gnu.org/55067.
