A single parameterized test is failing for the csingle and cdouble cases:

     @pytest.mark.parametrize('dtype', [single, double, csingle, cdouble])
      def test_types(self, dtype):
          x = np.array([[1, 0.5], [0.5, 1]], dtype=dtype)
  >       assert_equal(np.linalg.det(x).dtype, dtype)
...
RuntimeWarning: divide by zero encountered in det

Changing to draft to indicate that this is stuck until we can figure out what is going wrong

In case the logs go away before this gets revisited: the (failing) meson build here reports

clang 15.0.0 "Apple clang version 15.0.0 (clang-1500.3.9.4)"

while the (successful) cirrus CI one reports clang 16.0.0 "Apple clang version 16.0.0 (clang-1600.0.26.4)"
