Closed
Description
More specifically the opened connections count invariant assertion fails here. We expect to have no open connection at this point, however, I saw a negative connection count each time it failed.
I noticed that the connections were often released multiple times when in the .closed
state here.
I hit this against c9a9bf061d713c91ee9974fa8a6afe413acfd0e9
on macOS (Xcode 12 beta) and was unable to reproduce it against the swift:5.2 Docker image.
