Hi lovely sysadmins. Stem's Jenkins CI is frequently failing with segmentation faults...

Nick and I both attempted to reproduce this locally with the latest repos (stem commit 86d5578, tor commit 5e70c27) and they pass.

Per chance could this be related to our recent CI changes for #32879? It's unclear to me if python or tor is segfaulting. Maybe installing a different python 3.x version will help? Unfortunately without a local repro we're a bit stuck on how to resolve this.

On a side note, if Jenkins installs git we will be able to confirm what Jenkins is testing. Its test output has...

10:35:30 ======================================================================
10:35:30   stem version...                            1.8.0-dev
10:35:30   tor version...

10:35:30   operating system...                        Linux (debian 10.2)

... whereas if git is included the git versions will be added. Here's what I get locally...


  stem version...                            1.8.0-dev (commit 86d55785)
  tor version...                    (commit 5e70c27e)

  operating system...                        Linux (debian stretch/sid)

I wasn't really able to reproduce this yet. Will keep looking.

I came across at least one other issue, though: The test assumes it can listen on ports 1111-1113. If that doesn't work, it fails.
