So there seems to be some fixes in branch 1.1.0 after release of 1.1.0f, your code is no longer matching their git branch. Their new patch might be related, so maybe you can recompile the latest libssl from their 1.1.0 stable branch. Otherwise, although not really familiar with libssl internals, it doesn't look to be anything related to upper layer application, but only some internal/local stuff they try to clean on exit. It is not even on cleaning the tls context/connections -- that callback seems to be executed because is registered with `atexit()`. -- You are receiving this because you are subscribed to this thread.
