Comment (by gk):

 I uploaded testbuilds to people-tpo. I ran the Linux builds on three
 different systems and the Windows build on a Windows 7 machine. Everything
 worked fine. I had no chance to test macOS yet.

 https://people.torproject.org/~gk/testbuilds/21886/ has the bundles.

 I am still trying to understand why the fix is working and what the
 underlying issue of this ticket is.
