Segmentation fault in test using ESMPy on OS X
🐛 Bug Report
Hello again :) . While running Iris tests on OS X, I get a segmentation fault error from one of the tests of the ESMPy regridding function. Maybe this is OS-related, since I see that the same version of ESMF/ESMPy (8.2.0) is used in the CI and seems to give no issue on Linux.
I also see that the target Iris function is deprecated and it will be removed from future releases, so this is likely not so relevant - I thought I would anyway raise the issue in case somebody else bumps in the same problem.
How To Reproduce
On OS X, running the test_global_collapse from lib/iris/tests/experimental/regrid/test_regrid_conservative_via_esmpy.py:
pytest lib/iris/tests/experimental/regrid/test_regrid_conservative_via_esmpy.py -k "test_global_collapse"
gives me a segmentation fault

Expected behaviour
I see that the regridding in the test is expected to fail and to raise a ValueError within ESMF - however I get segmentation fault. ESMF also leaves the following log file, which I assume it's part of the expected behaviour:

I have noticed that adding ignore_degenerate=True as argument to ESMF.Regrid() bypasses the problem by skipping the problematic cells. The test still fails (the ValueError is not raised if ignore_degenerate is set to True) but I don't get segmentation fault.
