This seems to be working nicely. All ranks now have verbose test output, but only rank 0 actually outputs to the terminal. All ranks store the output to a file that's stored as an artifact. For example, https://gitlab.com/cscs-ci/ci-testing/webhook-ci/mirrors/4700071344751697/7514005670787789/-/jobs/8288337613 had test_multiplication_hermitian fail again with a segfault. The main output says srun: error: nid01590: task 2: Exited with exit code 1. If one then goes to the artifacts and looks at the log for rank 2 (ctest.2.txt: https://gitlab.com/cscs-ci/ci-testing/webhook-ci/mirrors/4700071344751697/7514005670787789/-/jobs/8288337613/artifacts/external_file/output/ctest.2.txt) it'll say in the backtrace:

with PopGTestTrace already quite a good hint as to what's going on. Not all failures actually print this, but at least there's higher chance of seeing it now.
