Description
This happens on master since the merge of #291 and all new PRs. I suspect a dependency update to be the cause.
For example https://travis-ci.org/open-telemetry/opentelemetry-python/jobs/623466280:
py37-tracecontext installed: aiohttp==3.6.2,async-timeout==3.0.1,attrs==19.3.0,certifi==2019.11.28,chardet==3.0.4,Click==7.0,Flask==1.1.1,idna==2.8,itsdangerous==1.1.0,Jinja2==2.10.3,MarkupSafe==1.1.1,multidict==4.7.0,requests==2.22.0,urllib3==1.25.7,Werkzeug==0.16.0,yarl==1.4.2
...
test_multiple_requests_with_illegal_traceparent (__main__.AdvancedTest) ... Segmentation fault (core dumped)
ERROR: InvocationError for command /home/travis/build/open-telemetry/opentelemetry-python/scripts/tracecontext-integration-test.sh (exited with code 139))
Note: this might indicate a fatal error signal (139 - 128 = 11: SIGSEGV) (exited with code 139)
Or https://travis-ci.org/open-telemetry/opentelemetry-python/jobs/623458269, where every test fails with:
