This is quite convoluted. I think the remaining bit of information missing is #14954. That PR modified the destructor of ClusterInfo which owns the last SSL socket context to be dispatched and deleted on the main thread. So it should be easy to delay manager_ destruction after dispatcher_ to fix this crash.
