segfault in NECI tests

[boegel]

The test step of NECI-20220711-foss-2022a.eb fails with segfaults when not enough memory is available:

The following tests FAILED:
         27 - test_neci_back_spawn_excit_gen (SEGFAULT)
         28 - test_kneci_back_spawn_excit_gen (SEGFAULT)
         29 - test_dneci_back_spawn_excit_gen (SEGFAULT)
         30 - test_mneci_back_spawn_excit_gen (SEGFAULT)
         31 - test_kdneci_back_spawn_excit_gen (SEGFAULT)
         32 - test_kmneci_back_spawn_excit_gen (SEGFAULT)

I saw this when ~44GB or even ~88GB is available.

I've tried forcing that only one test at a time is run by using ctest -j 1 instead of ctest -j, but that doesn't help...

Any ideas here @lexming?

Can we do better than somehow producing a helpful error message to suggest doing the installation in an environment with more available memory if the test suite failed?

Seeing this again when building NECI with GCC 12.3.0 (foss/2023a), via #21616, so I've reported this upstream:

• back_spawn tests failing with SEGFAULT ghb24/NECI_STABLE#18

Fixed in #21616 with patch:
