[New-bugs-announce] [issue31629] test_multiprocessing_fork failure on FreeBSD

[Serhiy Storchaka]

New submission from Serhiy Storchaka <storchaka+cpython at gmail.com>:

test_multiprocessing_fork fails only if run all tests on FreeBSD. It is passed successfully if run it separately.

$ ./python -m test -vuall
...
======================================================================
FAIL: test_many_processes (test.test_multiprocessing_fork.WithProcessesTestProcess)
----------------------------------------------------------------------
Traceback (most recent call last):
  File "/usr/home/serhiy/py/cpython3.7-debug/Lib/test/_test_multiprocessing.py", line 505, in test_many_processes
    self.assertEqual(p.exitcode, -signal.SIGTERM)
AssertionError: 1 != -15

======================================================================

----------------------------------------------------------------------

test_subprocess hangs, perhaps due to the same cause.
