I can reproduce the crash on my FreeBSD 12 VM:

vstinner at freebsd$ ./python -m test --fail-env-changed test_multiprocessing_spawn -v

FAIL: test_mymanager_context_prestarted (test.test_multiprocessing_spawn.WithManagerTestMyManager)
----------------------------------------------------------------------
Traceback (most recent call last):
  File "/usr/home/vstinner/prog/python/master/Lib/test/_test_multiprocessing.py", line 2754, in test_mymanager_context_prestarted
    self.assertEqual(manager._process.exitcode, 0)
AssertionError: -10 != 0
