It's not safe to access line editing state from the IO thread while inside readline() on the main thread. Remove the code that attempts to redraw readline after printing logs. This avoids segfaults during logging at the cost of those logs overwriting the prompt (this is not trivial to fix as readline is a blocking API). ================== WARNING: ThreadSanitizer: data race
