Not preventing merge of this PR, but I notice on my new machine Intel® Xeon(R) w3-2435 × 16 that -DCMAKE_BUILD_TYPE=Fast, which uses

cmake .. -G Ninja -DCMAKE_INSTALL_PREFIX=install -DPYTHON_EXECUTABLE=`which python` -DCMAKE_BUILD_TYPE=Fast -DNRN_ENABLE_TESTS=ON

-- COMPILE FLAGS | -O3 -flto -march=native   -fopenmp-simd

generates very many warnings and

$ ninja test
...
97% tests passed, 6 tests failed out of 199

Total Test time (real) = 163.73 sec

The following tests FAILED:
	  1 - unit_tests::testneuron (Failed)
	  3 - unit_tests::benchmarks (Failed)
	 16 - pytest_coreneuron::basic_tests_py3.12 (Failed)
	 72 - hoctests::test_neurondemo_py (Failed)
	 81 - rxdmod_tests::rxd_tests (Failed)

For another data point on an Apple M1 (Ventura 13.6, clang 15.0.0)

-- COMPILE FLAGS | -O3     -openmp-simd

many fewer warnings

It was my understanding that the test failure when using Fast is why Olli introduced FastDebug. It's a compromise forcing the compiler to generate really bad code, e.g. because it's not allowed to inline with Debug (cost: 10x), and allowing it to generate code that slightly changes the results, e.g. due to FMA or SIMD.
