I don’t seem to get your Actual Behavior:

I don’t seem to be getting the expected behavior, either.

Try changing the string length a bit, I also got the same results as you but after changing the string length a bit I eventually crashed, ^ 23 and ^ 27 did it for me. Maybe try running it a few times? Could be related to a race condition.

Bumping this because I found another function with the exact same issue.

The crash/freeze should now be mitigated. Thanks for reporting this bug!
