That looks like a similar example of the problem that bpo35378 solves. But the
PR is merged and the test keeps failing:
test test_venv failed -- Traceback (most recent call last):
File "/home/travis/build/python/cpython/Lib/test/test_venv.py", line 309, in
test_multiprocessing
out, err = check_output([envpy, '-c',

Running that command locally on master does not die with SIGABRT:
❯ ./python -c 'from multiprocessing import Pool;
