Issue #14563 has been updated by jeremyevans0 (Jeremy Evans).
I was able to reproduce this issue with the current master branch. I'm not sure why it occurs, though. The thread that is stopped (the main thread) is woken up by the thread that `IRB.irb` spawns before that thread exits. So I am not sure why this would cause deadlock. Interestingly, this issue only occurs on the first nesting. If you nest irb twice, then do Ctrl-C, Ctrl-D, it does not cause an error.
